[BUG] Peer node socketAddress is not updated when passed a new socketAddress

[martinsaposnic]

if the LSP node’s IP address changes, calling set_liquidity_source_lsps2 with the new IP doesn’t update the existing peer’s socket address. The node keeps trying to connect using the old one.

if self.peers contains node_id then it returns early:

pub(crate) fn add_peer(&self, peer_info: PeerInfo) -> Result<(), Error> {
		let mut locked_peers = self.peers.write().unwrap();

		if locked_peers.contains_key(&peer_info.node_id) {
			return Ok(());
		}

		locked_peers.insert(peer_info.node_id, peer_info);
		self.persist_peers(&*locked_peers)
	}
