 Running the test suite (`phpunit` on the command line) in full leaves
 several files remaining in the uploads directory once the tests complete:

 {{{
 /uploads/2021/03/waffles.jpg
 /uploads/2021/03/waffles-300x200.jpg
 /uploads/2021/03/waffles-150x150.jpg
 }}}

 Running only the media tests( `phpunit --filter Tests_Media` on the cli)
 leaves a different set of files remaining after they have completed:

 {{{
 /uploads/2021/03/test-image-large-scaled-150x150.jpg
 /uploads/2021/03/test-image-large-scaled-300x225.jpg
 /uploads/2021/03/test-image-large-scaled-768x576.jpg
 /uploads/2021/03/test-image-large-scaled-1024x768.jpg
 }}}

 I did try to tidy them up by deleting attachments manually in
 `_delete_all_data()` (similar to how posts are deleted between classes in
 `_delete_all_posts()`) but without success.
