    status/network: Add activate() to NMDeviceItem
    
    DeviceItems are sections, and therefore not actually activatable.
    
    However when we port to quick settings, those toggles will need
    to do *something*.
    
    For that reason, provide an activate() implementation that
    
     1. deactivates the device if currently connected
    
     2. delegates the action to the most-recently used item,
        the first visible item or the auto-connect item (in that
        order)
