Preflight Checklist

• [X] I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Problem Description

Music Together basically becomes buggy when app is closed before closing the session so this can help anyone be it a host or listener get back in their session without any troubleshooting when they closes the app or the app crashes for whatever reason, please refer to https://github.com/th-ch/youtube-music/issues/1826 to know hat I mean about music sessions being buggy

Proposed Solution

Auto joins after a start-up when app crashes and auto leaves when app is closed by user or app crashes

Alternatives Considered

any alternative solution would be to just not remember any previous session users and leave any session when app is closed by user or app crashes but this will require the users to manually join the host again which is a hassle so prior solution seems better in my opinion.

Additional Information

This could also solve https://github.com/th-ch/youtube-music/issues/1826 potentially by just kicking out all users when host leaves and auto joining kicked users when app is started by host again so they remember to close session next time they want to leave or just switch host to one of the listeners when host leaves.
