    Ensure that GtkIconView items get redrawn when the focus cell changes.
    
    Seems the redraw was not happenning from keynav when set_focus_cell()
    was called because keynav already updates the focus-cell. Now we
    just unconditionally redraw the focus item when set_focus_cell() is
    called.
