fix: compatibility change for edx-drf-extensions 9.0.0

edx-drf-extensions 9.0.0 requires VERIFY_LMS_USER_ID_PROPERTY_NAME
to be properly set in LMS to get the appropriate verification when
forgiving JWTs is enabled (which will soon be by default).

See openedx/edx-drf-extensions#408 for details.

This is part of:
edx/edx-arch-experiments#429
