Sergey Biryukov 0562036947 Tests: Correct the cache invalidation tests for old date or slug redirect.
This affects:
* `Tests_Rewrite_OldDateRedirect::test_old_date_redirect_cache_invalidation()`
* `Tests_Rewrite_OldSlugRedirect::test_old_slug_redirect_cache_invalidation()`

In the former test, the `$post_id` property is declared as `static`, so can only be approached as static, even when used within the same class in which the property is declared.

Using non-static access will result in `null`. See: https://3v4l.org/93HQL

This PHP notice was hidden so far, due to the existence of magic methods in the `WP_UnitTestCase_Base class`.

All the same, the magic methods as they were, would also return `null` for this property. All in all, the post being updated for this test would never get the correct `post_id`.

Fixed by using static access to approach the `static` property.

On a related note, the described bug fix (using the actual `$post_id` instead of `null`) exposed that this test was as a matter of fact failing. This was just hidden by the first bug.

Based on the original commit introducing the test, an adjustment is now made which appears to be what the test actually ''intended'' to test. A similar change is made to the cache invalidation test for old slug redirects. While not strictly required, it brings some consistency between the two tests and ensures that both tests use a unique `post_name` value to avoid collisions with the previous values.

This bug was discovered while fixing (removing) the magic methods in the `WP_UnitTestCase_Base` class in an effort to improve compatibility with PHP 8.2.

Follow-up to [53549].

<h2>First Things First</h2>
<p>Welcome. WordPress is a very special project to me. Every developer and contributor adds something unique to the mix, and together we create something beautiful that I am proud to be a part of. Thousands of hours have gone into WordPress, and we are dedicated to making it better every day. Thank you for making it part of your world.</p>

<h2>Installation: Famous 5-minute install</h2>
<ol>
	<li>Unzip the package in an empty directory and upload everything.</li>
	<li>Open <span class="file"><a href="wp-admin/install.php">wp-admin/install.php</a></span> in your browser. It will take you through the process to set up a <code>wp-config.php</code> file with your database connection details.
		<ol>
			<li>If for some reason this does not work, do not worry. It may not work on all web hosts. Open up <code>wp-config-sample.php</code> with a text editor like WordPad or similar and fill in your database connection details.</li>
			<li>Save the file as <code>wp-config.php</code> and upload it.</li>
			<li>Open <span class="file"><a href="wp-admin/install.php">wp-admin/install.php</a></span> in your browser.</li>
		</ol>
	</li>
	<li>Once the configuration file is set up, the installer will set up the tables needed for your site. If there is an error, double check your <code>wp-config.php</code> file, and try again. If it fails again, please go to the <a href="https://wordpress.org/support/forums/">WordPress support forums</a> with as much data as you can gather.</li>
	<li><strong>If you did not enter a password, note the password given to you.</strong> If you did not provide a username, it will be <code>admin</code>.</li>
	<li>The installer should then send you to the <a href="wp-login.php">login page</a>. Sign in with the username and password you chose during the installation. If a password was generated for you, you can then click on &#8220;Profile&#8221; to change the password.</li>
</ol>

<h2>Updating</h2>
<h3>Using the Automatic Updater</h3>
<ol>
	<li>Open <span class="file"><a href="wp-admin/update-core.php">wp-admin/update-core.php</a></span> in your browser and follow the instructions.</li>
	<li>You wanted more, perhaps? That&#8217;s it!</li>
</ol>

<h3>Updating Manually</h3>
<ol>
	<li>Before you update anything, make sure you have backup copies of any files you may have modified such as <code>index.php</code>.</li>

	<li>Upload the new files.</li>
	<li>Point your browser to <span class="file"><a href="wp-admin/upgrade.php">/wp-admin/upgrade.php</a>.</span></li>
</ol>
