gossip: Fix crash of getroute if we don't know any channels

Browse Source 
This happens when we either have no channel open, or didn't announce
the channel. This patch just fails the getroute request. I'll later
add the non-broadcast announcement for local channels that should fix
this for unannounced channels.
