connectd: Update connection list with new address

Browse Source 
If we're already attempting to connect to a peer, we would ignore
new connection requests. This is problematic if your node has bad
connection details for the node -- you can't update it while inflight.

This patch appends new connection suggestions to the list of connections
to try.

Fixes #4154
