This test asserts that, given a user that already has a staff CourseAccessRole in a course,
if that user has a CourseAccessRoleAssignment that describes a staff role in that same course,
that we do not mistakenly violate the unique_together constraint on the CourseAccessRole model by
creating a duplicate. As of now, this is handled by the CourseStaffRole code itself, which silently
ignores such duplicates, but this test is to ensure we do not regress.
