Ending the conference in a video room breaks the room in various ways

[robintown]

Steps to reproduce

Use the iOS or Android app to delete the Jitsi widget in a video room

Outcome

What did you expect?

Either that should not be possible, or the video room should continue functioning as intended

What happened instead?

The room breaks in a number of ways, including:

• Participants currently on the call don't get removed from the call, resulting in a splitbrain scenario if additional people then try to join after the deletion
• Sometimes the room view is entirely blank
• Connection state gets stuck in weird ways
• iOS and Android apps may try starting native Matrix calls if you then tap on the video button in the room header
