Always shuffle quiz matching question matches

Closes CNVS-4342

TEST PLAN
---- ----

  - create a quiz with:
    + a matching question and 3 pairs of answers/matches and a bunch of
      distractors
    + infinite multiple attempts
    + shuffle answers option turned OFF
  - take the quiz by a student:
    + look at the order of the matches
    + submit and re-take
      + verify that the order of the matches has changed (if not, you
        may just been hit by the RNG wand, try again)
  - turn on the option to shuffle answers and verify the matches still
    shuffle like they did without the option
