Steps to reproduce the bug:
create a new run with a publish date in the future, submit for review
as an admin user, set the status to Reviewed
as the course editor user, confirm the that front-end status shows as "Scheduled", change the course price
note that the run status goes back to "Unsubmitted"
Price is a field that should be exempt from changes bumping Reviewed runs back to Unpublished / Unsubmitted
