Fix bug 1828.
Fix bug 1828.

Somehow, long ago, we were sending the scmtool to the inline review form
template. This wasn't actually used anywhere, and blew up with graphics-only
review requests.

Testing done:
- Tried a graphics-only review and saw the review form pop up as expected.
- Tested making several comments on a diff review and published via the "Review"
  button.
- Ran unit tests
