Quiz regrade attempts needing it causes Incorrect number of query parameters error with groups.

You need a course with two groups, G1 containing Student S1, and G2 containing S2. As admin/teacher, create a quiz set to separate groups mode. Add two true-false question, set the right answer to True. Twice, once as S1 and once as S2, attempt the quiz. As admin/teacher, edit both questions, and change the right answer to False. Go to Quiz administration -> Results -> Grades. Select group G1. Click "Dry run a full regrade for group 'Odd group'". Click"Regrade attempts (1) marked as needing regrading in group 'Odd group'" Verify that S1's attempt is regraded. Verify that there were no DB errors. Verify that there were no developer debug notices about making the first column unique for get_records. Note, there will probably be a developer debug notice about doing output before redirecting. Given the way we want to display a progress bar, I think that is unavoidable. (If you have a good idea how to fix that, please open a new MDL. Thanks.)
