tdf#118150 Fix displaying of chart where Legend is set manually

By default Legend's position is automatic and it is located
at the right side of the chart.
Unfortunately even if layout with manualLayout is set:
http://www.datypic.com/sc/ooxml/e-draw-chart_manualLayout-1.html
the empty space for the automatic legend on the right side of the chart,
was left.
This is issue with opening of the OOXML charts by LibreOffice,
as MS Word is opening the same document properly.

This patch fixes issue with wrong chart displaying, when manual position
of the legend is set.
