tdf#117274 XLSX export: fix VML comment shape type id
to avoid shape multiplication in a mixed environment.
MSO needs the special unescaped VML comment shape type
id "_x0000_t202" to avoid of generating also DrawingML
shapes from the VML ones. Calc export escaped the shape
type ids ("_x005F_x0000_t202"), keeping also the DrawingML
shapes, so every round trip between LO and MSO resulted
more and more broken shapes in the document.
