Fix Review UI sandbox tests.
Review Request #7177 — Created April 7, 2015 and submitted
A few of the unit tests for sandboxing of review UI methods were broken on
release-2.5.x. The cause appears to be a difference in caching between the
file attachment'sreview_uimember and the file attachment comment's
review_uimember. I've cleaned this up to make sure we're spying on the right
thing. While I was in here, I also fixed up some bad naming.
Ran unit tests.
