Allow accepting accepted revisions, and rejecting rejected revisions
Summary:
Ref T1279. With the new per-reviewer status, you can always accept or reject a revision.
This is primarily cosmetic/UI changes. In particular, you've always been able to reject a rejected revision, the UI just didn't show you an option.
Test Plan: Accepted accepted revisions; rejected rejected revisions. See screenshots.
