    status/network: Simplify notification code
    
    There is only one case where we show a notification: When activating
    a connection failed.
    
    There is therefore no reason for a generic wrapper around the
    notification API. Likewise, tracking the source is a bit pointless,
    given that the notification is transient. In fact, as we destroy
    an existing notification *before* checking for the source, any
    previous source will be gone by that point.
