The above exception was the direct cause of the following exception:

@abhi1693 are you aware of the custom user model work being done for v4.0 under #12795? Can this issue wait until 4.0 so that we avoid a merge conflict?

[abhi1693]

I'm aware but this is a simple fix and without this my plugins will not work on v3.7.x. Besides it doesn't change the functionality but makes the code consistent and I don't think it should create any conflict as only the class names have been fixed
