tdf#80340: Table changes format in PPTX format

Problem:
- If the PPTX contains embedded table i.e copied from excel, when we open it in
impress it row height increase due to this table format changes.
- Table contents empty row i.e without text, then row height increase because
text height is added also added for empty row.

Solution:
- Added check whether row contents text or not.
