ln gossip: don't put own channels into db; always pass them to fn calls 
Previously we would put fake chan announcement and fake outgoing chan upd
for own channels into db (to make path finding work). See Peer.add_own_channel().
Now, instead of above, we pass a "my_channels" param to the relevant ChannelDB methods.

b55f9e9e6a Do not route through channels for which we did not receive 
both updates, because this often means one of the nodes is
offline.

f2d58d0e3f optimize channel_db: 
- use python objects mirrored by sql database
 - write sql to file asynchronously
 - the sql decorator is awaited in sweepstore, not in channel_db

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
