Pressing the button with no coins inserted leads to generating a QR-code

[Danstrg]

Just a little check needed if coins have been inserted before generating the Qr-code

[AxelHamburch]

This problem is already fixed. If no coins are inserted and the button is pressed, the "display.update_nocoin_screen()" screen is called up. See app.py line 88.
