"AppRegistryNotReady: Apps aren't loaded yet" exception after 3.7.1 -> 3.7.2 update #5564
Description
Steps to reproduce
- Clone/checkout this PR (which updates django-rest-framework from 3.7.1 to 3.7.2): Update djangorestframework to 3.7.2 mozilla/treeherder#2917
- Push to a Travis-enabled GitHub repo
(Or to reproduce locally, clone/checkout, install Virtualbox/Vagrant then vagrant up && vagrant ssh then ./manage.py check inside the VM)
Expected behavior
Travis tests pass, like they do on 3.7.1 (which is on master):
https://travis-ci.org/mozilla/treeherder/builds/297971608
Actual behavior
The ./manage.py check step fails with:

Plus the pytest step fails with the same exception and similar traceback too.
