    CamelIMAPXServer: Handle unsolicited VANISHED responses.
    
    By "unsolicited" here I mean there are no commands in progress which
    would otherwise emit the folder change notification when the command
    completes.  In that situation, emit the change notification directly
    from imapx_untagged_vanished() rather than holding it until the next
    command completes.
