Resolve "Adjust join room when room is not existing"
Closes #85 (closed)
Proposed changes
- Adjusted the room joining so that you can't enter a room which is not existing
For testing
- Login as participant
- try to join a room with no room-id => you should get an invitation to enter a id
- try to join a room with an invalid room-id => you should get an invitation to enter a valid id
- you should be able to join a room which exists
