MDL-32791 quiz db: clean up garbage data that was causing problems.

Melinda Kraft reported having rows in their quiz_question_instances
table which caused various problems. These rows are meaningless, so I
have done a DB upgrade step to clean them up, which should deal with the
bad side-effets they were causing.
