    window: Don't accidentally destroy panels when showing overview
    
    When passing --overview, Settings' new shell window accidentally
    removes the newly selected panel.
    
    We're considering the possibility of adding an overview page but,
    since that won't happen for the next release, let's just make sure
    something happens for now.
    
    Fix that by simply changing the panel list view, which selects the
    Wi-Fi panel if the user was in another view.
