Stop reporting error from mime sniffing when a fetcher completes with no data

Browse Source 
If a fetcher returns with no data (no content or http error code 204)
the hlcache state machine was trying to mimesniff using non existent
header data and reporting the resulting NSERROR_NOT_FOUND as a
"BadType" message.

This changes the behaviour to be similar to that in the headers
received case where NSERROR_NOT_FOUND from the mimesniffing is not an
error.
