Also fix a bug in `Context::GetClassType` that previously tried to complete the class type before returning it. That's not correct -- `GetCompleteTypeImpl` is only appropriate for cases where the type can trivially be completed and completing it can't fail -- and led to infinite recursion with this change because we would call `GetClassType` when producing a diagnostic if completing that class type failed.
