Various call fixes

- If peer invited us claiming audio-only and then wants to have a video content, do a content-modify and accept audio-only
- Check contents for video (and modify) and whether call is truly accepted in PeerState.accept() directly
- If a message contains both JMI and CIM, only use JMI
- Fix outgoing CIM (disabled)
- Use opacity instead of visiblity for file_menu, small fixes
- Add back owner/admin/member queries when joining MUC (regression from 33104a7)
