Add method to get refund transaction reference

Merge pull request #17 from jason-nabooki/patch-1

Fix exception if refund status is an error

Fix refunds

This fixes an incorrect change in the previous release, which broke refund functionality if using the getTransactionReference function to get the transaction ID for the refund.

Fix ListTransactionsRequest endpoint

The ListTransactionsRequest class is updated to match the other request classes, and uses listTransactionsWithHttpInfo instead of the deprecated listTransactions function.

Note that the getTransactionReference function has been updated to get the order ID instead of the transaction ID - this may be considered a breaking change, but since the transaction ID was the wrong thing to return, it's unlikely this function is currently being used.
