fix issue with republish quiz not working correctly pre-draft state

fixes CNVS-13391

test plan:
  - turn off draft state
  - as a teacher
    - create a new quiz
    - publish the quiz
    - make changes to the quiz questions
    - make sure the notification shows that you have unpublished changes
    - republish the quiz
    - the quiz changes should be published

  - make sure there are no regressions with CNVS-13003

  - make sure that publish/unpublish of a quiz with DS continues to work
    as expected
  - mess around with any way you can think to publish the quiz via modules
    etc.
