    Remove false runtime check in ews_connection_notification_start_thread()
    
    It is false when there are multiple objects sharing the same connection,
    each subscribing to its own folder, then when one is freed it unsubscribes
    from its folder, but the others are still listening for the changes, which
    means the notifications are started again, without freeing the notification
    object in the caller.
