Exit screen for Payments

At present, when a payment is processed which is applied to more than one invoice, when the payment is saved the system exits to the Payments screen, so it is easy to continue with the next payment.

When the payment is applied to just one invoice, saving exits to the Invoice screen, when means that one must then first click on the Payments menu option on the left before being able to add the next payment.

It would be great to have the behaviour consistent, and exiting to the Payments screen would be better than exiting to the Invoices screen.
