Saleor: Successfully paid orders are no longer redirected to the success page

[NyanKiyoshi]

What I'm trying to achieve

Get the "Thank you for your order!" message after the user successfully paid.

Steps to reproduce the problem

1. Make an order;
2. Pay it;
3. It doesn't redirect to payment_success anymore.

What I expected to happen

To get redirected to the payment_success.

How should we handle the payment success? Should we always say "Thanks for your payment!", or should we redirect the user back to the order?

I don't have a strong preference actually but personaly I would recommend saying thank you and add a link to view the order. This is an explicit way to indicate the users that the payment is successful. Redireting users back to the order directly sounds a little bit confusing for the users about the status of the order.

This must be a bug after recent changes in payments. We should definitely fix this.
