Editing a student with grace credit deductions fails

[daneshd]

This is a routing error when trying to edit a student. It tries to give you the ability to edit the result (i.e. the submission) so that you can remove the grace credit deduction while editing the student.

To reproduce:

1. Setup an assignment where a group/student has used 1 grace credit. Easiest done when there already is a on day X, modify the assignment due date to day X-1 and recollect.
2. Go to the users tab and edit the student, you'll see a route error.

Here's an example on sandbox[1] but I don't know how long that will stay unchanged.

Assigning to myself since I'm modifying the partial associated with this page anyway.

If you haven't made progress on this, I'll take a look at it?

Sure, assigning it to you.
