Feedback form generation sometimes gives all 0s for manual Q

Data file to reproduce on my gdrive (memory jog for later)

After some debugging:

• it seems TA-specific -- so all the assignments in one or two grading accounts will have the issue, and most TA grading accounts all will be fine
• it seems that if I re-run feedback generation with --force on the repro examples, it fixes the feedback form.

I think the next thing I have to do is collect the docker console output from the feedback form generation and see if any warnings/errors are reported. Maybe if the feedback form grade doesn't agree with the DB grade I'll print the docker console.

If nothing comes up there I think I'll just bandaid-fix it by making feedback generation check whether the grade in the feedback form agrees with the grade in the DB and re-run the feedback form gen if not.
