If a request fails, we populate response end, but response start can be null. It is counter-intuitive to have a null response start with a non-null response end.
Assigning to mgersh@ to triage.
I fixed this by renaming response end to request end, which is a better description of what it is. It's https://codereview.chromium.org/2401933002/, which I forgot to associate with this bug.
