[FAB-5197]Check all prop-responses in balance-transfer

"balance-transfer" app doesn't check all of the proposal responses.

An app sends a transaction proposal to multiple peers and get
multiple responses. However, the only first response
"proposalResponses[0]" is checked repeatedly in the loop.

This patch fixes the code to check all of the array value of
proposalResponses correctly.
