The LocalSite permission wrapper broke on Django 1.6, due to

PermLookupDict renaming module_name to app_label.
This updates our calls to use the new name. It also adds unit tests to

ensure we catch any breakages in the future.

Ran just the unit tests on the master branch, without the fix, and got

the same errors that were silently triggering our permission lookup

failures.
Ran with the fix, and the tests passed. I was also able to choose

Delete Permanently, and close another user's review requests.
