Unit Tests:

* Automatically delete objects that we were created during `wpSetUpBeforeClass` - posts, comments, terms (except 1), and user (except 1)
* The amount of leftover data between tests was breathtaking - use the new function: `_delete_all_data()`
* Commit database transactions for all `TestCase`s, not just those that implement `wpSetUpBeforeClass` and `wpTearDownAfterClass`
* The tests run 10-20 seconds faster now

See #37699.
