Also copy `__module__` to our dynamically created TestCase subclass when override_settings acts as a class decorator.

Otherwise, an error in e.g. a test in tests/modeltests/proxy_model_inheritance/tests.py

ERROR: test_table_exists (django.test.utils.ProxyModelInheritanceTests)

Refs #16672 and [16650].
