FWIW, the migration file two_factor/migrations/0009_initial.py is still being generated, because of the URLs in two_factor/urls.py. If I remove them too, no migration is generated any more.

Sure, this is not sufficient to solve the migration issue. However I separated from #596 as this is IMHO not subject to any discussion, while the rest of the #596 PR might have some backwards compatibility issues.
