#25733: Change of inherited model's primary key not spotted by makemigrations

----------------------------+--------------------
I have an inherited model - class Speaker(Person) - where Person is from a
third party module. That module has updated, changing their ID from
implicit to an explicit id CharField, but updating that module and trying
to migrate fails because it says "Key columns "person_ptr_id" and "id" are
of incompatible types: integer and character varying".
Presumably I need a migration in my module to change the implicit
OneToOneField to be a CharField to match, but "makemigrations" doesn't
find any change needed, it's still an integer.
