839c3f7 [rpc] Remove signrawtransaction warning (John Newbery)

Pull request description:

  Removes some deprecated code from the RPCs:

  - signrawtransaction was deprecated in 0.17 and removed in 0.18. A warning message was left in place to advise users to use signrawtransactionwithwallet and signrawtransactionwithkey. That warning can now be removed.
  - validateaddress had some functionality deprecated in 0.17 and removed in 0.18. The help text for that functionality was not removed in 0.18 and can be removed now.
