No audioCallEnded event (or any other event) when the meeting ends

[fridaybyte]

Describe the bug
No event that would correctly indicate that the Meeting has ended (has been deleted). Thus there is no way for apps to quit meeting properly if the server (another party) has ended the call.

To Reproduce
Steps to reproduce the behavior:

1. Run demo mobile (android or iOS) app on one or more devices
2. Join the same meeting
3. Delete this meeting using API

What actually happens

• app stays on the meeting screen for 30 seconds. Only after 30 seconds demo app goes back to the main screen
• onVideoSessionStopped is called immediately, but with VideoServiceFailed status
• onAudioSessionStopped is called only after 30 seconds, with AudioDisconnected, which is again described as failed leg

Expected behavior
After the meeting is deleted:

• demo app detects that the meeting has ended and goes back to the main screen immediately.
• audioSessionDidStopWithStatus is called with audioCallEnded or audioServerHangUp

Test environment Info (please complete the following information):

• Version amazon-chime-sdk: 0.22.6
• Version amazon-chime-sdk-media: 0.17.10
• Can you reproduce this in the demo app? Yes

Additional context
This forces all attendees to manually quit the meeting. There is no way to automatically end a call for all attendees by the backend or by one of the attendees (e.g. host). This works properly on JS SDK.
