In this commit, we fix three existing bugs in the way we make
`ResolutionReq` for breach handling:
1. We were passing in the commit blob of the *current* channel state,
instead of the one stored in the revocation log for this breached
state.
2. We were using theirDelay for CsvDelay, when we want ourDelay, which
in this case will be 1 CSV, as this is a non delayed output.
3. We also need to pass in the delay for the remote party's to_local
delayed output.
This will be used by external callers to modify the way we resolve
contracts on chain. For a given contract, we'll store an extra "blob",
that will later be presented during the sweeping phase.
