Looks like HasCache returns false with NO_ERROR when not found. So
ToWebServiceWorkerCacheError will DCHECK.

[michaeln, 2014/08/12 03:59:23]

nit: the type translation to blink'ish speak (WebServiceWorkerCacheError and
widestrings) is something that seems like a function of the renderer process. i
probably should have mentioned that in an earlier review.

[jkarlin, 2014/08/12 15:17:48]

Looking at service_worker_messages.h it looks like we always send string16 over
IPC. Shouldn't this be too?
