The first hop is being stripped from computed routes, however the
first channel of the route is being used to get our peer address. This
results in segfaults if the route is just one hop, i.e., has no first
channel to get the peer's address from. Fixed by simply using an
existing pointer to our peer.
This allows hardcoded routes in the config file, which is required until
we get route advertisements.

We're about to change the code so that if it can't route, it will fail
the HTLC. The current low-level tests will hate this, so have a dev switch
to turn that off.
