smartcontract: (un)marshal AnyType value as null

Browse source 
Neo 3 can emit Null in its transfer notifications in `from` or `to` fields
when minting/burning tokens (unlike Neo 2 that emitted util.Uint256{} for this
case), then it gets converted to Parameter as AnyType and we have to JSONize
it somehow for proper RPC functioning.
