CAR-1805:Pass payment object to error-creationresults.

[ahalberkamp]

I have fixed this bug in the pr:

1) Scenario

• A US-Customer insert a Address with a wrong City/State combination like New York/Alabama
• Then he selects paypal as paymentmethod and submit his order

2) Problem

• After submitting payone complains about the wrong City/State combination
• Then the paymentmodule processes the response and checks if the response contains the "paypal redirect" url, which of course doesn´t exists because of the city/state error. So it generates a "PaymentTransactionCreationResult.ofError" with the following errormessage:"here was no redirect set at the payment object which is required for Paypal"
• This creationresult is now pass to the shop, and so the Shop only gets the errormessage about the missing redirecturls, because the payment modul swollow the Rootcsause

3) Bugfix: To solve this problem, I have appended the payment-object to the "errorcreationresult", so that the shop can fetch the rootcause of Error, when a payment was not successfull.
