    network: Fix all Wi-Fi networks having gear buttons
    
    Only the networks with existing connection should have gear buttons.
    This is a regression from 9ffaff74724aafe29a836b472dd682e6156ef00f.
    
    If the widget we add as a stack page isn't visible, the page will not be
    shown. As we later add another page with that button, we'd end up
    showing that by default.
