The chaincode packaging function wrongly implies that the packaging
operation is performed on a peer when it is in fact done locally.
This change fixes that.

go chaincode now sets the Asset owner as client identity certificate string (instead of base64 str)
Reason for the update: "GetClientIdentity().GetID()" api in go chaincode returns base64 string, while same api in java chaincode returns the same data as string
go & java chaincode sets same owner string
updated js app verify method

Added check to avoid double spent in token-utxo chaincode

In the transfer function it was possible to pass the same utxo more than once in the array of input utxos without any error. Making it possible to spend the same utxo more than once in the same transaction and like this create more tokens than minted. To fix this I changed the array that was used to store the input utxo states to a map and so utxos were stored in the map by there key, which made it possible to know if a key and so a utxo had already been used.
I tested this by setting up the test-network, deploying the token-utxo chaincode with my fix, minting a utxo and trying to spent this utxo more than once in the same transaction, which was not possible anymore. It can only be spent one time anymore with this fix.
