Jb Audras 5aee8db5a2 Script Loader: Remove default DNS prefetch entry for s.w.org.
A default DNS prefetch entry for s.w.org was previously included to save a few ms in case an emoji is used that is not supported by the browser. It appears this use case doesn't justify a prefetch to s.w.org on every WordPress website.

This changesets removes `emoji_svg_url` prefetch from `wp_resource_hints()`. It also updates unit tests in `Tests_General_wpResourceHints` by removing `test_should_have_defaults_on_frontend()` entirely and removing s.w.org prefetch from expected output of ten other test functions.

Plugin authors can use the `wp_resource_hints` filter if they need to re-add the DNS prefetch entry for s.w.org.

Follow-up to [37920], [38122].

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.
