tdf#94804 sw: allow duplicate heading cross reference bookmarks

... in ODF import, so that reference fields do not break that reference
numbering cross reference bookmarks that were corrupted by commit
679faffc68bb854af0f55d0f218698e2f372f00b.

This used to work by accident before commit
9d0c51daea67104349cac26de9839afa8baeb099 fixed it to actually check for
duplicates properly.

(cherry picked from commit 7c3c3006deaaaf1bb3f2f4eeeaf11da3bcebe53c)
