34988	Makemigrations shouldn't prompt for default values for non-nullable fields of other apps.	Sarah Boyce	Bhuvnesh	"Have more than one app (app_1 and app_2). In app_1 have a model that has it's migrations applied then add a field that doesn't have a default and is not nullable (do not run makemigrations).
Then add a new model (or anything that would require a migration) to app_2.
Run `manage.py makemigrations app_2`

You get prompted for every app that has unapplied migrations missing defaults even though you're running migrations for a different app. 
I would expect it not to care, as you can input temporary defaults to all these other apps and it doesn't do anything with them.

I think this might be a test case:
