    network: fix Add Connection dialog
    
    The Add Connection widgets from the connection
    editor dialog weren't properly using the available
    space, since they don't expand.
    
    Fix that by making them expand and fill the available
    space properly. It also avoids blank space by vertically
    centering the list.
    
    
    
    (cherry picked from commit 6e6e9952b4e6b1a3715254ee3fd131db7d8b0594)
