If Group model has been swapped, django tries to create a new migration during makemigrations

[jacklinke]

Describe the bug
If the Group model is swapped, and then the makemigrations command is run, django attempts to create a 7th migration within django-automations

Expected behavior
Running makemigrations within an end-user's project should have no effect on django-automations. All migrations should be provided complete with the package.

Additional context
I think I've got the issue sorted out, which involves manual creation of a new migration with:

• dependency on migrations.swappable_dependency(settings.get_group_model_setting()),
• an AlterField operation modifying the interaction_group field with to=settings.get_group_model_setting()
• and finally, change in django-automation's settings to how the group model is retrieved

The last thing I'm still trying to pin down is the testing. After I get that resolved, I'll submit a PR to correct the behavior.
