Reduce reliance on getRevisionID() on DifferentialComment

Summary: Ref T2222. A few rendering interfaces rely on fishing the revision ID out of a DifferentialComment, but it will only have the PHID soon. Pass in the revision and use it to determine the ID instead.

Test Plan: Browsed, previewed, examined comments. Clicked anchors.
