tdf#100275 sw: fix target node of bookmark copy

Replaces the defensive programming band-aid of
5c1a1d1c66aff497702abc20df5832fa348f1008 with a real fix.

The problem is that lcl_NonCopyCount() has some special case code
to ignore the first node in the target document, which erroneously is
executed for every bookmark, which results in the 2 bookmarks in the
bugdoc being created with nDelCount 1 and 2 so they land on the same
node, which is not allowed for cross-reference marks.

Extract the adjustment into a separate function that is called once.

(regression from 689962feae2054f965a7378c3408b0ccfad2bbd5)

(cherry picked from commit bc387975b11d87868884ec770a2a42a4f7092b5f)
