    assistant: use gtk_widget_hide() instead of popover API
    
    We don't use gtk_popover_popup() anywhere else, so keep symmetry by using
    gtk_widget_hide() too. The only value right now that I see with the
    popover variant is that it could end up cascading to the root which
    isn't something we necessarily want.
