Tonya Mork 06dc5e170f Template: Fix "undefined index: 00" when archive month query is empty in wp_title().
When `m` query_tag has a valid year, i.e. `?m=2021`, and there are posts for that year, `substr()` returns a `false` on PHP 5.6 and an empty string on PHP 7.0+. Passing either of those values to `$wp_locale->get_month()` results in a PHP notice on PHP 5.6 to PHP 7.4 and a PHP Warning on PHP 8.0+.

Why? The `$month` lookup table has zeroized keys from '01' to '12'. A empty value is passed to `zeroise()` returns `'00'` which is directly passed as a key in the month property. That key does not exist.

While `$wp_locale->get_month()` would benefit from guarding/validation, this fix ensures a falsey value is not passed as a month.

Tests are added including a test that fails with this fix not applied.

Follow-up to [801], [35294], [35624].

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.
