This else block is now exactly the same code as the previous block, except for a local variable name and the input data (tokenReceivingOutputs vs tokenChangeOutputs)

It could be refactored to deduplicate the common code out out the branching, and just keep the branching to assign the input data

let tokenOutputs = tokenReceivingOutputs;
// Parse token self-send txs
if (tokenReceivingOutputs.size === 0) {
    tokenOutputs = tokenChangeOutputs;
}
