6bbdbf7596 rework on_channel_closed in LNWorker: 
- use detect_who_closed; this allows us to redeem to_remote of breach ctx
 - do not redeem to_local of breach ctx, because it is redundant with lnwatcher
 - rename a few methods

aa398993cf lnrouter fixes: 
- use gossip_queries_req instead of initial_routing_sync
 - add connected nodes to recent peers only after successful init
 - derive timestamp used with gossip_timestamp_filter from channel_db
 - fix query_short_channel_ids:
     1. channel IDs must be sorted with zlib
     2. limit request to 100
     3. do not abuse this to request node_announcements; it is fine not to have all nodes.
 - fix get_recent_peers:
     1. do not set last_connected_date to 'now' if we never connected a node
     2. sql query was misconstructed and was returning only one peer
 - populate FALLBACK_NODE_LIST_MAINNET with nodes that have the requested flags
