Sergey Biryukov 7f08fac299 Tests: Correctly back up and restore theme directories in Tests_Theme.
In the `set_up()` method, a copy would be made of the original value of the global `$wp_theme_directories` variable, with the intention to restore that original value in the `tear_down()` method after running each test. Unfortunately, this was not implemented correctly.

* The backup is made to a function local variable in `set_up()` and not stored somewhere where it is accessible from the `tear_down()` method.
* The restoring then references a non-existent property to restore, which would effectively set the `$wp_theme_directories` global to `null`.

Fixed by declaring and using a private property to store the original `$wp_theme_directories` value.

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 [38907].

The short version:

1. Create a clean MySQL database and user. DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.

2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.

3. $ svn up

4. Run the tests from the "trunk" directory:
   To execute a particular test:
      $ phpunit tests/phpunit/tests/test_case.php
   To execute all tests:
      $ phpunit

Notes:

Test cases live in the 'tests' subdirectory. All files in that directory will be included by default. Extend the WP_UnitTestCase class to ensure your test is run.

phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run. This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs. Pure unit tests may be used also, of course.

Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.

phpunit is intended to run at the command line, not via a web server.
