interstitial.malware.decision is polluted with extra SHOW counts

Project Member Reported by nparker@chromium.org, Apr 5 2017

Issue description

There are a handful of clients that increment the SHOW bucket on malware interstials without the PROCEED or DONT_PROCEED buckets, and it messes up our CTR metrics.

This affected Windows first (all channels) starting 2017-03-08, and then all desktop client on 2017-04-02

Conversations about the spike on Windows:

ops: https://groups.google.com/a/google.com/d/msg/chrome-safebrowsing-team/M_NfQ-38qpI/v6OkSxQcEAAJ

Dremel suggests this is getting worse, now with 187 clients reporting more SHOW-(PROCEED+DONT)>20 in one day. The max discrepancy is 1700, meaning 1700 interstitials somehow without closing the interstitial.

Looks like a similar thing is now happening on Android for interstitial.phishing.decision:

On Android, "SHOW" was hovering around 52% but recently stepped up to 57%.

I'm starting a thread with finch-users to discuss this since it is affecting the PVer4 launch metrics.
There's a recent spike in interstitial.malware.decision = {SHOW}

FWIW: I am only seeing a mismatch for interstitial.malware.decision, not for phishing
