When making an XML request to `getTransactionListForCustomer` instead of returning the expended response title of `getTransactionListForCustomerResponse`, we instead get the title `getTransactionListResponse`. This is causing an issue with the ActiveMerchant ruby gem as it expects the request title, and response title to correspond consistently.
This issue can even be replicated in the API console here (just be sure to select XML, it doesn't seem to affect JSON): https://developer.authorize.net/api/reference/index.html#transaction-reporting-get-customer-profile-...
