fix ChartDocumentWrapper::createInstance

which I broke in
    commit fe37aa64ff79abcd3aeedeb03d8d74798225a367
    Date:   Sat Jan 15 13:45:44 2022 +0200
    use more concrete types in chart2, ChartView

by copying behaviour from the wrong construction site.

And then in
    commit c592574948b0a28bac965b508bc260aaa6c365d3
    Date:   Sun Jan 16 12:25:49 2022 +0200
    use more concrete types in chart2, ChartView

I spread the error further by using the incorrect behaviour I had
introduced in
the first commit in Chart2ModelContact::getChartView()
