tdf#107618 DOCX export: fix missing header when doc ends with section

See commit b6e62dc0dc2b284c825f1182a67bb2f9259a30ce (tdf#106492 DOCX
export: fix duplicated section break at doc end, 2017-03-21) for the
context, this is one more case where it's not OK to suppress the two
section breaks at the end of a document, since the suppressed section
break is the one that provides the headers / footers.

(cherry picked from commit 2a73e7d88c19cab69733a4f6433d8576856285ac)
