Handle review request summary info without timestamps.
Review Request #9701 — Created Feb. 25, 2018 and submitted
Old review requests from years back didn't track the closing times of
review requests. This broke the new review request status information
code, which assumed a valid timestamp to parse and display. The old
mechanism ignored this due to templates in Django 1.6 silently ignoring
failures.Now, if the timestamp for a close is
None
, we just won't attempt to
show timestamp information.
Unit tests pass.
Tested with review requests that were closed but lacking close info.
