Django-oauth-toolkit: Lazy reference issues when swapping the application model on Django 1.10

[bastbnl]

Hi,

I'd like to thank you for this app and your support. Much appreciated.

I'm running into some lazy reference issues when I try to swap the application model on django 1.10. I believe I've followed the steps outlined in https://django-oauth-toolkit.readthedocs.io/en/latest/advanced_topics.html. I'm running into some migration issues when I try to create a migration to add the new model. Here's the output:

The field oauth2_provider.RefreshToken.application was declared with a lazy reference to 'app.brownpaperapplication', but app 'app' doesn't provide model 'brownpaperapplication'.

I've changed the setting and added the model

OAUTH2_PROVIDER_APPLICATION_MODEL = 'app.BrownPaperApplication'

Can you help me?

I found the solution while writing this PR but decided to go ahead filing the PR anyway.

The solution was actually quite simple. First add the swapping model and create and run the migration. Then change the setting to swap the model.

I followed the steps specified here and in the google groups forums: https://groups.google.com/forum/#!msg/django-oauth-toolkit/a5qTWOctc2A/5X6zapo-NgAJ

I manage to create the vendor but I get a Related modelapp.MyApp` cannot be resolved. Has anyone encountered this issue too?
