fdo#68963 recognize __RefHeading__ bookmarks as TOC in .doc files

LibreOffice recognizes MS Office Table Of Contents, but LO files
saved as .doc didn't show the Cross-Refence heading - it was blank.
Now bookmarks using the LO naming convention are also imported
as TOC bookmarks from .doc files.

Testcase included.
