[REV] pos_restaurant: stop closing paymentscreen while paying

Revert of
https://github.com/odoo/odoo/pull/92794

If you install pos_restaurant and open a PoS sale session, issue will start to appear after a certain time (about 1 minute):

For V15:
Javascript console logs will log errors:
`TypeError: Cannot read properties of undefined (reading 'id') Chrome.js:97`

For V15.2:
The products button will become unresponsive (so the PoS is unusable).
With error in the JS console as well:
`TypeError: Cannot read properties of undefined (reading '0') Chrome.js`
