[7.0] payment order not refreshed after adding invoice

[Stéphane Bidoul (Acsone)]

Hello,

When adding invoices to payment orders, the payment order is not refreshed immediately: one needs to save, close and reopen the payment order to see its content correctly.

How to reproduce:
- runbot 7.0
- validate a supplier invoice
- open the existing draft payment order
- click Select Invoices to Pay
- select a date after the due date of the supplier invoice
- click Search then Add
- select a supplier invoice
- click Add to Payment Order
- result: the payment order contain no visible lines
- expected result: the payment order should contain the selected invoice
- note that when reopening the payment order, the line is there, so its a UI refresh issue
