Editing quiz bank question unlinks question bank from quiz

[MatthewFuller]

I realize that title might have been hard to follow, but it was the best I could do at the moment!

Here's the issue we're seeing:

- Designer creates a bunch of questions in a Bank
- Designer links the bank to a specific quiz
- Designer finds an error in a question and edits it in the Bank
- Editing the question causes the entire Bank to unlink from the quiz, so they have to go back in and fix it

Is there a fix for this, or a fix for this on the roadmap? Please let me know if you have other questions.

Thank you!
