SmartArt: remove calculateHierChildOffsetScale() from org chart algorithm

Its purpose was to center subtree if sibling parent has no children.
It was not working correctly for complex charts causing shapes to overlap.
Without it chart is still readable (just sometimes not centered).
Remove it for now until more universal solution is found.
