    generic updates: Fix old updates accumulating in the OS Updates item
    
    When we first get an update to version 1, and a while later to version 2
    of the same app, both of them would accumulate in the "OS Updates" item.
    
    This was due to the use of plugin cache in the generic updates plugin
    which kept the "OS Updates" from a previous get_updates call still
    around and never removed the old apps from it.
    
    Fix this by changing it to create a new "OS Updates" proxy app every
    time.
