Related: tdf#115719 DOCX import: fix increased spacing vs left-aligned objects

Commit 8b73bafbc18acb4dd8911d2f2de8158d98eb6144 (tdf#115719 DOCX import:
increase paragraph spacing for anchored objects, 2018-02-14) added an
import-time tweak for a problem that has been confirmed to be a Word
layout bug in the meantime (and the tweak makes Writer behave the same
way if the document has been created by an affected Word version for
layout compatiblity).

Later, commit 4883da6fd25e4645a3b30cb58212a2f666dae75a (Related:
tdf#124600 DOCX import: ignore left wrap on left-aligned shapes,
2018-02-14) fixed left spacing of anchored objects aligned to the left,
to be in sync with what the DOC import does.

This broke the previous fix in case the shapes are left-aligned.

Fix the problem by tracking what is the in-file-format and logical left
margin, so the final doc model has the value necessary for correct
horizontal positioning and the importer has the value that's necessary
for correct vertical positioning.
