Fix close descriptions on older review requests.
Review Request #2456 — Created July 8, 2011 and submitted
Fix close descriptions on older review requests. The logic for determining the current close description text broke on older review requests. It assumed that the latest change description was a status change, but this wouldn't be true for any older ones. It would happily use the text, which was confusing. Now the view checks specifically for a proper status change, and passes the appropriate text as a "close_description" parameter to the template. The template no longer has to know about the latest change description when figuring out the text.
Tested this on some older review requests, and on some new ones with recorded status changes. It was no longer grabbing the wrong text on old ones, but still got the right text on new ones.
