Jitsi link generation broken with unusual names

Summary

When a students with an unusual name (e.g. with a ' in the name) creates a new request with an automatically generated Jitsi link, this link will give a 404.

Steps to reproduce

1. Login with a user which has ' in the name.
2. Create a new request which has Jitsi as room.
3. Enter the generated Jitsi room and see the 404.

Possible Fix

Remove all the alphanummeric characters from the name before using it to generate the Jitsi room name.
