Fix loading of serialized comments for the image review UI.
Review Request #8573 — Created Dec. 14, 2016 and submitted
The image review UI sends its serialized comments as an object rather than an
array, which wasn't at all clear from the code, and only emerged when I
actually tried to use it. I've changed the code back to using_.each
to
iterate over it, and added a comment as to why.
Was able to use the image review UI again.
