[FIX] point_of_sale: Open Cashdrawer when no printer is selected
[FIX] point_of_sale: Open Cashdrawer when no printer is selected

- In the POS config, check "Receipt Printer"
- The "Cashdrawer" checkbox will show, check it
- Uncheck "Receipt Printer"
--> Cashdrawer is still checked, so if you open the POS and validate
an order paid in cash, it will try to open the cashdrawer, but there's
no receipt printer so the command fails with a traceback.
