Don't QuizQuestion#question_data= for aq update
Don't QuizQuestion#question_data= for aq update

Looks like QuizQuestion#question_data= is expecting form data and
create_quiz_question uses write_attribtue so update_assessment_question!
probably should also.

Fixes CNVS-19292

Test plan:
 - Full regression test all quiz question types through question banks
 making sure to also edit the question bank for every question type.
