go chaincode now sets the Asset owner as client identity certificate string (instead of base64 str)

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
