Make sure to always fix up the MEDIA_ROOT after admin tests.
Review Request #4584 — Created Sept. 17, 2013 and submitted
Make sure to always fix up the MEDIA_ROOT after admin tests.
If UpdateTests.testManualUpdatesRequiredBadUpload fails (say, due to something
being rendering the base.html template), it will leave settings.MEDIA_ROOT and
siteconfig's site_media_root in a broken state. This breaks a bunch of other
tests, which is highly confusing.
Ran into this case when working on my django1.5 branch, and this fixed it.
