QR Code Scan triggers next Code, even if already submitted
How to reproduce:
- A voter scans a QR code, but does not immediately access the URL.
- The Manager clicks submit to generate a new QR code
- The next Voter wants to scan the QR code
- previous Votes now opens the URL and the currently next QR code is not anymore shown
Problem: The QR Code generated in the meantime is not used.
