Protect against uninitialized variable or None value in two error cases in post-review 0.2RC1
Review Request #1427 — Created Feb. 22, 2010 and submitted
Line 128: 'err' in self.rsp would trigger "TypeError: argument of type 'NoneType' is not iterable" if rsp in None Line 419: rsp is not initialized but is used at lines 427 and 432 (fall through). I also moved the last debug message into an else: under try: as a Review is not created in the fall through case.
Verified both error cases. Verified that a review request is correctly updated if --diff-file option is used with a changenum but no review id.
