Thanks Florian for isolating the shortest way to reproduce this issue:

Returning None on errors required unpythonic error checking and was
inconsistent with get_app_config.
get_model was a private API until the previous commit, but given that it
was certainly used in third party software, the change is explained in
the release notes.
Applied the same change to get_registered_model, which is a new private
API introduced during the recent refactoring.
* Introduced [un]set_installed_apps to handle changes to the
INSTALLED_APPS setting.
* Refactored [un]set_available_apps to share its implementation
with [un]set_installed_apps.
* Implemented a receiver to clear some app-related caches.
* Removed test_missing_app as it is basically impossible to reproduce
this situation with public methods of the new app cache.
Since the original ones in django.db.models.loading were kept only for
backwards compatibility, there's no need to recreate them. However, many
internals of Django still relied on them.
They were also imported in django.db.models. They never appear in the
documentation, except a quick mention of get_models and get_app in the
1.2 release notes to document an edge case in GIS. I don't think that
makes them a public API.
This commit doesn't change the overall amount of global state but
clarifies that it's tied to the app_cache object instead of hiding it
behind half a dozen functions.
Currently, if the authentication mechanism uses a custom HTTP header
and not REMOTE_USER, it is not easy to test. This commit modifies
remote user tests in order to make them more generic.
Current language is no longer saved to session by LocaleMiddleware
on every response (the behavior introduced in #14825).
Instead language stored in session is reintroduced into new session
after logout.
Forward port of c558a43fd6 to master.
Added a validation error check when creating the permissions for model, to avoid
cryptic database error when the verbose_name is longer than 39 characters
