tdf#90575 sw: fix pasting DDE links

Regression from commit 0761f816 (123792:
complete annotations on text ranges feature, 2013-12-19), the problem
was that the added additional IDocumentMarkAccess::GetType() check in
lcl_FindDdeBookmark(), which means that the function no longer finds
bookmarks with the matching name, only real DDE marks. This is a
problem, as SwTrnsfrDdeLink::WriteData() depends on the fact that
sw::mark::Bookmark inherits from sw::mark::DdeBookmark. As a result, the
fast IDocumentMarkAccess::GetType() (that intentionally doesn't handle
inheritance for performance reasons) can't be used here.
