[FAB-5913]balance-transfer:Fix query response message

"queryChaincode" doesn’t output responses from all
peers in log message. It exits the loop processing after
outputting the first response.
We should print all responses from all peers. Also, we should
return a response (e.g. the response_payloads[0]) after the loop.

This patch fixes the problems above.
