tdf#120551 DOCX import: fix position of group shape with absolute position

Regression from commit af313fc1
(tdf#105143 DOCX import: enable DoNotCaptureDrawObjsOnPage layout compat
option, 2017-01-06), the group shape which covers most of the single
page in the document had a negative left position, while it should have
a small positive one (checking the drawingML markup).

This was a pre-existing problem, but now it's visible since we no longer
force objects to be on the page in Word compat mode.

Seeing the ODT import never positions group shapes (it's just a
container for child shapes), probably the DOCX import shouldn't do that
either. Start moving into this direction, first only for
absolute-positioned toplevel group shapes only, which already fixes the
bug.
