DOCX import: fix lost objects anchored to an empty linked header

This is really similar to commit
04b2310aaa094794ceedaa1bb6ff1823a2d29d3e (DOCX import: fix lost objects
anchored to the single para of a linked header, 2020-01-10), except here
the header is not just a single-paragraph one, but has no text portions.

Update text-copy.docx to have a header which is not only a single
paragraph, but also has no character content. This keeps testing the
original case, but now also tests the more strict case (single paragraph
-> single empty paragraph).
