This is just a possible space for catching user errors and warning about
them.
I have two apps, a backfill migration created with --empty and using
RunPython in app A is using apps.get_model to get a model from app B.
However the migration has no dependency on app B.
Depending on runtime ordering of migrations this may cause a LookupError,
or it may work.
It feels like apps.get_model could be noticing that based on the
dependency graph the referenced app/model may not exist.
