Tests: Correct a flaky wp_nonce_field() test.

The test for `wp_nonce_field()` with a custom action name verifies that the nonce value matches the one returned by `wp_create_nonce()` with the same action name.

The created nonce, in turn, depends on `wp_nonce_tick()`, which returns a different result in the first and the second half of the nonce's lifespan, one day by default:
* 00:00:01 to 12:00:00 — First tick
* 12:00:01 to 00:00:00 — Second tick

In practice, due to a delay between initializing data providers and running the actual tests, it is possible for the nonce tick to change in the process, for example if the test suite run starts at 11:59:30, and the affected test runs at 12:00:30, causing a test failure.

This commit reduces the chance of a race condition by moving the `wp_create_nonce()` call from the data provider into the test itself.

Includes wrapping long lines with the expected results for better readability.

Follow-up to [54420].
