Reduce logging when signing transactions

Browse source 
1. We can generalize the signing interface by passing a PSBT in
instead of the `TxLock` transaction.
2. Knowing the transaction ID of a transaction that we are about
to sign is not very useful. Instead, it is much more useful to know
what failed. Hence we add a `.context` to the call of `sign_and_finalize`.
3. In case the signing succeeds, we will immediately broadcast it
afterwards. The new broadcasting interface will tell us that we broadcasted
the "lock" transaction.
