7d5125c935 lnwatcher: fix tx replacement and notifications 
- revert the logic of do_breach_remedy to what it was
   before 0ca3d66d15,
   but now calling self.maybe_redeem unconditionally.
 - replace mempool transactions only if the fee increases
 - do not notify the GUI if a local tx is replaced
 - delete labels when replacing

2c962abe51 network: randomise the order of address subscriptions 
Before this, we were subscribing to our addresses in their bip32 order,
leaking this information to servers. While this leak seems mostly harmless,
it is trivial to fix.

3a35f90aa0 Do not use network callback to update channel states; call LNWorker methods directly instead. 
A callback was used because a single LNWnwatcher object used to be shared for all wallets.
Since wallet now have their own LNWatcher instance, this can be simplified.
