onchaind: fix all_irrevocably_resolved test.

Browse Source 
I was examining a test_onchain_timeout failure, and realized that we
were forgetting a peer even though we'd just spent the HTLC_TIMEOUT_TX!

This reveals that we weren't resolving an output when we stole the preimage
from it, like we should.
