Expected Behavior

When the room gets unloaded and the current queue is empty, the current queue should become the previous queue. In other words, when the current queue is empty, the previous queue should be saved as empty upon room unload.

Steps To Reproduce

1. create a permanent room
2. add videos
3. unload room so prev queue gets saved
4. load room
5. see previous queue restored (referred to as queue A)
6. remove all videos from queue, including currentSource
7. unload room to try to get prev queue saved
8. load room
9. see queue A is restored when it should be empty

Environment

• This happens on the official site, opentogethertube.com
• This happens using a self-hosted version.
• I'm using the docker image.
