- store the ctn of sweeptxs in sweepStore database
- request the highest ctn from sweepstore using get_ctn
- send sweeptxs asynchronously in LNWallet.sync_with_watchtower

7be4cdaf18 redeem htlcs: 
- fix bug in lnsweep: lnwatcher transactions were indexed by prev_txid
 - add test for breach remedy with unsettled htlcs
 - add timeout option to lnpay, and replace DO_NOT_SETTLE with SETTLE_DELAY
   so that we can read intermediate commitment tx in regtest

6211e656a8 lnwatcher: do not get_transaction before broadcast 
this workaround was inserted to avoid losing the interface
when rebroadcasting a transaction already in the mempool
many times. but since the network should make sure we always
have a interface ready, and this problem shouldn't happen on
mainnet, remove the workaround

795ba1f99d lnwatcher: ensure probable spendability of prev_tx 
previously, we would try to publish the second_stage
even if we couldn't, because a conflicting transaction
was published (like an htlc success when we close with
htlcs pending with a 1-hop payment and an online
counterparty)
