The message "user_unshared_webcam_message" is generated when a user unshares his webcam.
If a user is sharing the webcam and leaves the conference by closing the conference window/tab, this message is not generated.
However, if the user leaves the conference by clicking the "sign out" button, then the event is properly generated.
This issue does not happen for the voice conference events. Even if the user closes the window all "left voice" events are generated.
