Revert of Set proper result (purple/red) for "Uncaught Exception" and "Failure reason" steps

Revert of Set proper result (purple/red) for "Uncaught Exception" and "Failure reason" steps (patchset #1 id:1 of https://codereview.chromium.org/2142833002/ )

Reason for revert:
Broke sheriff-o-matic (https://screenshot.googleplex.com/td2M1aXN8S4); it caused a bunch of duplicate alerts to show up.

I believe we can cause the step to turn purple without having it show up as a failing step, which incorrectly triggers a lot of our sheriffing tools.
