Repro:
(1) Start up device and/or sign out to get to the sign-in screen.
(2) Wait for a while (usually takes around a minute or two).

Expected: Sign-in screen remains visible.
Actual: DCHECK() crash.

Looks like the crash is:
DCHECK_LE(pipeline_reporting_frame_times_.size(), 25u);

DCHECK()s are now enabled by default for all developers (go/dchecks-on-by-default), so this is a P1.
