BUG/MEDIUM: cache: do not try to retrieve host-less requests from the cache

Browse Source 
All HTTP/1.1 requests the Host header share the same hash key 0 and
will be return the first cached object. Let's add the check on the call
to sha1_hosturi() to prevent this from happening.

This must be backported to 1.8.
