[gnome-software] Only set the app row's buttons as destructive when they remove an app

[Kalev Lember <klember src gnome org>]

    Only set the app row's buttons as destructive when they remove an app
    
    If the page is set as colorful, we should still not show the update
    button as destructive. So it should only be set as such when the app
    is installed (because the button will remove the app).
