Return FaultException for invokefunction and invokescript RPC calls

[roman-khimov]

Summary or problem description
This one intersects a little with the recent neo-project/neo#1881. We shouldn't forget about our regular invokescript and invokefunction RPC calls that could also make use of FaultException message. After neo-project/neo#1761, neo-project/neo-node#621 and neo-project/neo-node#630 it is possible to get this additional data for local executions, but not for remote which is a little unbalanced.

Do you have any solution you want to propose?
Add a field containing this message to invoke* calls results.

Where in the software does this update applies to?
