show "no_score" icon if turnitin check is pending, fixes #9844

fixes regression in gradebook around default turnitin icon (and brings gb2
in line)

test plan:
1. set up turnitin on an account and assignment
2. submit homework as a student
3. as a teacher, check gradebook and gradebook2
4. you should see a gray turnitin icon (until the turnitin report gets
   generated)
