Change in usage on transactionId vs transactionRef

[eileenmcnaughton]

In discussion on
thephpleague/omnipay#261
I have determined the CiviCRM Omnipay plugin has been using transactionReference where it should have been using transactionId.

I have updated the Cybersource plugin (e.g https://github.com/dioscouri/omnipay-cybersource/pull/19/files) but you should review this change in conjunction with gopay

Thanks for the report. The processor is unused right now and I haven't looked at the code for some time so I'll fix this issue when/if somebody uses the processor again.
