Allow resubmitting to plagiarism platform for anonymous grading

Closes PLAT-3647

Test Plan:
- Enable  the 'Anonymous Grading' FF in your root
  account
- Create an assignment with a plagiarism detection tool.
  Be sure to select the 'Graders cannot view student names'
  option when creating the assignment.
- As a student submit to the assignment.
- Create a pending originality report for the submission.
- In speedgrader click the "resubmit to <tool name>" button.
- Verify the page refreshes and a `plagiarism_resubmit` live
  event was emitted.
