M/C regrade in classic quiz should not trigger duplicate submission in speedgrader

[NicolaFroese]

In classic quizzes, regrading a multiple choice question will create a duplicate submission in speedgrader for all students despite the students' submissions remaining the same after the regarde.

This screenshot shows a submission in speedgrader before and after regrading a m/c question.

Removing this result of a m/c regrade will help avoid confusion for instructors when grading exams that have student essay or file submissions and also require a m/c regrade.

Thanks for sharing this feedback about the regrading process in Classic Quizzes,  @NicolaFroese . Our product teams are no longer developing new functionality on the code base for Old (Classic) Quizzes, which is scheduled for deprecation, so we've archived this idea. Please read through the resources in the New Quizzes User Group to learn how you can get started with the new quiz tool.
