Validate RPC result on merged_output_data

[Syther007]

Currently we are zipping responses, hashes_and_paid_amounts & accounts based on order then matching the response for a successful or failed transaction.

The hashes in the responses should be matched against the hashes_and_paid_amounts.
To make things easier we should zip hashes_and_paid_amounts with accounts and pass this new vector as a new argument into the merged_output_data function.
