The JSON-RPC was non-standard compliant in that it omitted the required
`jsonrpc` entry and it was returning both `error` as well as
`result`. This fixes both of these issues.
This is less convenient to use, but makes far more sense for a real
user (like a wallet). It can ask about the route, then decide whether
to use it or not.
This will make even more sense once we add a parameter to control how
long we let the HTLC be delayed for, so a client can query for high,
medium and low tolerances and compare results.
