tdf#129221 DOCX import: fix missing restart of numbering

Regression from e49d2b31fb2020d065b4ad940d1031d07b10f32b (fdo#78939
[DOCX] Hang while opening due to incorrect modification of Style,
2014-06-06), the problem was that the 2nd sub-list of the bugdoc was not
restarted in Writer, while it was in Word.

The PR2 paragraph style inherits from the PR1 one and only that sets the
numId; tweaking the bugdoc to state the numId directly in PR2 would work
around the problem.

Fix the issue by improving DomainMapper_Impl::finishParagraph(), so that
it uses lcl_getListId() rather than calling
pStyleSheetProperties->GetListId() directly; since the previous knows
how to walk up the parent chain if needed.
