Fix prerender byte-count UMA.

In the review process of cr/160513002 I wound up losing reports of bytes from non-prerender resources.  This fixes that.  It also updates the max bin size of profile bytes since there could be lots of requests between prerenders.

Show the extension / app name for platform verification.

The platform verification dialog communicates to the user the origin of
the request.  Normally this is a web origin but for extensions or v2
apps the web origin is ugly and the extension / app name is better.
