can't delete user after removing app

[Larry Martell]

I have a django project that has many different apps. We deleted one
of the apps, and now when we try and delete a user it fails,
complaining about a table from that app not existing. There are no
references to that app, or table anywhere. Testing, I found that if I
create the table the error goes away.

After googling and searching around I thought I had figured it out.
The app was referenced in django_content_type and the content_type_id
was referenced in auth_permission. So I deleted the rows with that
content_type_id from both auth_permission and auth_permission, but I
still get the error. I also made sure the permission rows I deleted
were not referenced in auth_user_user_permissions or
auth_group_permissions.

What do I need to do to remove references to this app so I can delete users?

Here is the full stack trace:
