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.

06dfe1699c LNWatcher: Distinguish between blockchain-triggered channel state 
transitions, and actions taken as a result.

- peer actions are in LNWorker.on_channel_update()

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.
