Check failure details don't show in 'pebble checks' when failures==threshold #634
Description
When the failure count is exactly the threshold, pebble checks doesn't provide information about the failure.

@benhoyt pointed out that it's happening because it's switched to the new change ID (13) but there are no failures on that change yet (they're still on 12).
It would be nice if we could improve this somehow.
