Fix style renaming confusion in ww8 filter (solves fdo#63603)

- Mapping LO default style to Word "Normal" style for docx output used a
  hard coded style name, so it broke when LO's default style was renamed
  in 4.0 (plus it would never have worked for non-English languages)
- This renaming did not cater for nameclashes, leading to fdo#63603
- Similar renaming when importing doc styles did cater for nameclashes,
  but had a minor bug in that
