Sergey Biryukov 21c38bb6b3 Tests: Minimize file copying in WP_REST_Attachments_Controller tests.
The tests use two images that were deleted on teardown and recreated on setup for every single test. This appears to be unnecessary, as the files can instead only be recreated if they are missing, and deleted after the test run is complete.

This commit reduces ~200 redundant file copying operations to ~5 when running this test class.

Follow-up to [38832], [48291], [54424].

See #55652.

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.
