Issue description

The transaction's source address is missing from the response body.

Resolution

The sourceAddress parameter only populates when a transaction's status is one of the following:

• Completed
• Rejected (if it has already progressed through the Confirming status)
• Failed (if it has already progressed through the Confirming status)

Additionally, for UTXO transactions, the sourceAddress parameter only populates with one source address even when the incoming transaction inputs were sent from several addresses. This source address will always be the address that contributes the most inputs or the highest amount of the asset.
