[REVIEW-3-5] Text color in shapes (pptx import)

[Muthu Subramanian K]

Hi,

It will be great if someone can cherry-pick this fix for n#746996, please?

Summary: Text color is imported wrong when there are none specified. We 
should use default color settings (in pptx - i.e. tx1) instead.

Thanks & Regards,
Muthu Subramanian
