4294e70690 rawtransaction: fix argument in combinerawtransaction help message (Matthew Zipkin)

Pull request description:

  Minor correction in the help message provided for `rpc combinerawtransaction`. The input to the rpc is not an array of transaction hashes (txids) but an array of serialized transactions encoded in raw hex.
