fdo#83664: svx: don't try to paint on empty OutputDevice

ObjectContactOfPageView::DoProcessDisplay() initalizes an empty
aViewRange, which later code assumes to mean "paint everything", but
actually the OutputDevice has 0 size so nothing can be painted.

Actually we shouldn't always set Overlap flag on for all xlsx charts...

The correct fix unfortunately would require making the axis label layout
smarter, to avoid overlapping of angled text label objects.
