peer: check for ErrEdgeNotFound when loading chan edge for fwrding policy

Browse Source 
This commit adds a precautionary check for the error returned if the
channel hasn’t yet been announced when attempting to read the our
current routing policy to initialize the channelLink for a channel.
Previously, if the channel wasn’t they announced, the function would
return early instead of using the default policy.

We also include another bug fix, that avoids a possible nil pointer
panic in the case that the ChannelEdgeInfo reread form the graph is
nil.
