Title: Class Registry ignores duplicate matching classes

This is what Robo and I figured would work for the jobs0 error. We are getting an error sometimes for unknown reasons that the class UserGroup is already in the registry. It appears to be trying to import the same module again, so this change prevents the error if a matching class exists and bypasses the callbacks if so.
