    tdf#134973: restore unmodified status of chart on export
    
    Upon first save, the chart model may get modified during export when
    accessing subtitle which gets created when not yet existing. That
    modified state hadn't been reset previously, when the save was done
    in the DocxAttributeOutput::WritePostponedChart.
    
    Prior to 129f55097f926661f00919329fb28c6a85ecebbb, because of double
    insertion of the same object, EmbeddedObjectContainer::StoreChildren
    stored the duplicate of the chart again (after the "modification"
    happened in DocxAttributeOutput::WritePostponedChart), and reset the
    status in ChartModel::impl_store. The mentioned commit made the old
    problem manifest itself.
