Referencing user before user migrated on new projects

In dotKom/onlineweb4 we get the exception

Which probably means that redwine is referencing our custom user model before the table for our own apps are migrated.

This happens when installing and migrating the referenced project for the first time. I can not reproduce this in a simple django project which uses the default user model from django.contrib.auth.
The fix for now is to remove redwine from installed apps, then migrating, adding redwine back to installed apps and migrating again. That works.
