Tests_Media::test_media_handle_upload_sets_post_excerpt() should delete test image

[ocean90]

Tests_Media::test_media_handle_upload_sets_post_excerpt() was added in [31694]. The test uploads a file "test-image-iptc.jpg" which should be deleted after the test was run.

This patch should delete the test image once the test has been run.

Question - once a ticket is assigned, what does that mean? What is the process supposed to be from here on out? Forgive me if this is out there on in documentation, I've just not found it. Thanks.

@McGuive7: In the case of this ticket, it's been assigned to you because it's considered a good-first-bug for new contributors, and you've "claimed it" by adding a patch. At this point, you're waiting for core developer feedback.

Thanks @DrewAPicture. And are the core devs just constantly reviewing all open tickets? Man, that is a lot of tickets :) Is there any resource out there you can recommend to help me better understand this process?

In 32794:

Clean up uploaded file after test_media_handle_upload_sets_post_excerpt().

Props McGuive7.
Fixes #32534.
