Fixed #34816 -- Fixed GenericForeignKey crash when checking cached for primary keys with different types.

[oguzhanakan0]

Following the suggestion in ticket/34816, changed the logic while accessing a GenericForeignKey to skip checking PK match if ContentType IDs do not match.

Test function is placed in tests/generic_relations_regress.py.

Unit test output before the patch:

During handling of the above exception, another exception occurred:

Everything seems to be working, thanks to rlaager for the suggestion and @felixxm for the test function.

P.S. This is my first contribution so please let me know if I missed anything. Thanks-

Thanks for the patch, make sure change the MR description to point at 34816 and not 34813.
