fn credit_registration_config(
course_code: &str,
with_product: bool,
) -> CreditRegistrationSeedExpand description
Turns the module on and points it at the mock’s realisation for the same course code.
with_product is per module because open_university_product_access_tokens is keyed on the
product id globally: two modules sharing one would let a spec that breaks the token refresh break
another spec’s enrolment link.
