    Fire off loading user images after chooser is mapped
    
    The update_visible_items function calls gtk_tree_view_get_visible_range
    which seems to only work after the tree view is mapped.
    
    This commit makes sure that we queue an update after the widget is
    mapped.
    
    (seems to a fix a problem where users face icons don't always show up)
