If I understand managers and migrations correctly then the change in this
commit https://github.com/tolomea/django-
tutorial/commit/e5df712ef10be91cd2e5d28c9df48e33254a2b10 produces a bad
migration.
Specifically I expect the migration to include both managers but it omits
the "objects" manager.
This causes a problem in the followup data migration
https://github.com/tolomea/django-
tutorial/commit/90825038c55913d74a23b1c5c2ba35268d0a1367 where
Question.objects isn't available leading to {{{AttributeError: type object
'Question' has no attribute 'objects'}}}
I have observed this in 3.0.8 and 2.2.14 (where I first ran into it)
