lnworker: fix type error re pending_payments, and impl malformed htlcs

In old code, in lnpeer.htlc_switch(), "error" in lnworker.pending_payments
had incorrect type.

Fix detection of payments.
...
1. In lnhtlc, sent_in_ctn and failed_in_ctn need to look at the
remote ctx, and they need to be called when we receive a revocation,
not when we send one.
2. In lnchannel, we use 3 lnworker callbacks:
- payment sent/payment failed (called when we receive a revocation)
- payment received (called when we send a revocation)
3. Make revoke_current_commitment return a single value.
The second value was only used in tests, there is no need
to bloat the code with that
