No feedback after Bb test work around

There was a bug that can be overcome by re-initiating the feedback (taking it off and putting it on again in Edit Test Options).

1. mouse over the test where the students see it
2. click the menu button that forms
3. edit test options
4. scroll to feedback and take off all checkmarks
5. submit
6. mouse over the test again
7. click the menu button that forms
8. edit test options
9. scroll to feedback and put back on the checkmarks that you want
10. submit
