Assignment upgrade fails during 1.9 course restore conducted by a teacher




      When conducting a course restore from 1.9 and merging into an existing course, the assignment upgrade fails.

      This seems to affect teachers only. When an admin attempts the restore, it succeeds.

      Replication steps:

      1. Create a new course or us an existing course (empty or with existing content)
      2. Enrol a teacher
      3. Log in as that teacher
      4. Navigate to the course
      5. Restore the attached course
        • Choose to merge into the current course (or delete the content of the course)

      Expected result: The course should restore and the assignment should upgrade without error.

      Actual result: The restore fails showing an error upgrading the assignment.

      This seems to affect 2.7 and the current master (pre-2.8) but does not affect 2.6 (and presumably earlier versions).
