So that CcPanel implementations have a method to add their subpages to the builtin CcPanel.navigation. Hub panels like System and Privacy have their main landing page composed in an AdwNavigationPage. Therefore we overwrite the CcPanel.child setter to add these pages to CcPanel.navigation instead of overwriting CcPanel.child like we do for all the other panels.
