The `esc_url()` function expects to a string for `$url` parameter. There is no input validation within that function. The function contains a `ltrim()` which also expects a string. Passing `null` to this parameter results in `Deprecated: ltrim(): Passing null to parameter #1 ($string) of type string is deprecated` notice on PHP 8.1+. Tracing the stack back, a `null` is being passed to it within `next_posts()` when `get_next_posts_page_link()` returns `null` (it can return a string or `null`). On PHP 7.0 to PHP 8.x, an empty string is returned from `esc_url()` when `null` is passed to it. The change in this changeset avoids the deprecation notice by not invoking `esc_url()` when `get_next_posts_page_link()` returns `null` and instead sets the `$output` to an empty string, thus maintain the same behavior as before (minus the deprecation notice). Adds a test to validate an empty string is returned and the absence of the deprecation (when running on PHP 8.1+). Follow-up to [11383], [9632].
