oox smartart, org chart: handle multiple paragraphs on data node

This problem was similar to the one fixed in
cfa76f53 (oox smartart, accent process:
handle multiple runs from a data point, 2018-11-21), but this there we
handled multiple runs and this handles multiple paragraphs.

It seems some smartart types allow multiple paragraphs in a diagram
node, others only allow multiple runs. Org chart is in the former
category.
