Sergey Biryukov c73c0916dd Tests: Reset timezone-related options if the tests change them.
The `options` table is not explicitly reset after each test or test class, so if an option is changed during a test, it should be reset to the default value ''after'' the test.

This commit does so for those tests which did not have such resetting in place yet, while one or more tests in the class ''do'' change the value of the `timezone_string` option.

Note: The test suite executes a `ROLLBACK` query after each test, which should reset the `options` table in theory, however that appears to not always be enough, as some timezone-related tests can fail in a complete test suite run, while not failing when run in isolation. This commit aims to improve stability of the tests.

Follow-up to [45857] / #45821.

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.
