Fixes #9282

It looks like super() checking is too strict for methods with self-types. Mypy explicitly allows self-type annotation to be a supertype of current class, so to be consistent, I relax the check for super() as well.

Looks great! Just a minor nit about the is_self_type_like function -- I think the code might be more readable if the parameter is named is_classmethod rather than is_class :-)
