Roman Khimov 5b470f14cc rpc: pass single Param to CreateFunctionInvocationScript
N3 contracts require method and array of arguments to function correctly, but
CreateFunctionInvocationScript can produce scripts that won't work correctly
if one is to pass anything but a single array parameter to it. This doesn't
make much sense, so we can always expect there to be an array of parameters in
the third positional invokefunction argument (the same way C# node does).
