tdf#127778 DOCX import: fix unexpected heading on non-first page ...

... when the first page has a heading

Regression from commit 17e51f427b3f0cec74ac8e0a1b3f51189006ae6f (DOCX
import: first page header should always set default headers as well,
2014-11-21), the problem is around how to split a first + follow page
style on import, and then do the opposite on export.

This is described using a single section in OOXML, but Writer has 2 page
styles for this (unlike in case of the DOC filter). This means the
header margin has to be taken from one of these page styles. The above
commit tweaked the import, so the follow page style has the wanted
header margin, but this leads to incorrect layout.

Fix the problem by tweaking the export instead: it has random access to
the doc model, so it can take the header margin from the first page
style if needed, and then the import side can be reverted, leading to
correct layout.

Also remove some leftover debug code in test/, which was added in commit
5352d45dd4a04f8f02cf7f6ad4169126d3b3586a (convert AnimationImport to
fast-parser APIs, 2020-02-18).
