tdf#100072 zero height of shape's path was causing geometry errors

DOCX custom geometry shape's path width and height are now used
independently for scaling calculations.

(cherry picked from commit 5477f7274e4df1210298c0f503a54eabc0f06bfc)

plus:

tdf#100072 extra test for DOCX shape import with zero height

Corresponding bug is already fixed in tdf#107104. However created
tests do care only for width, but not for height, like we have in
this testcase.
