Fix loading of serialized comments for the image review UI.
Review Request #8573 — Created Dec. 14, 2016 and submitted — Latest diff uploaded
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_.eachto
iterate over it, and added a comment as to why.
Was able to use the image review UI again.
