Subject: [PATCH] channeldb: in RestoreChannelShells don't exit if edge already
 exists

During the restore process, it may be possible that we have already
heard about our prior edge from a node on the network (or our channel
peers). As a result, we shouldn't exit if this happens, and instead
should continue with the rest of the restoration process.
