Sample ODT

The attached ODT has a custom property set: "Company" is "Test_x005f_".
(without quotes)

- Save ODT as DOCX.
- Reload DOCX.
- Check the property.

=> It becomes "Test_x005F_x005f_".
Upon further reload-save cycles, it keeps growing (Test_x005F_x005F_x005f_,
Test_x005F_x005F_x005F_x005F_x005f_,
Test_x005F_x005F_x005F_x005F_x005F_x005F_x005F_x005f_ etc.)

Observed using LO 6.3.0.0.alpha0+ (0c0e73584f125025fb17d6be8f8050f3b7649c7d),
5.4.0.3 / Ubuntu 18.04.
No issue with LO 5.3.0.3.
=> regression
