        Django Fakery: User Model: YELLOW (raises IntegrityError)

        We have to push the number of Users created, but since Django Fakery
        has no collision protection and uses a small number of latin words it
        will always fail sooner or later. Sometimes on the second user.

        However, instances created are valid if they are able to enter the
        database.
