tdf#123313 sw: workaround Undo problem with ToX Update

The problem is that when ToX is updated, CrossRefHeadingBookmarks will
be created for the heading nodes, and SwUndoInsBookmark will be created
at that time, but then nodes will be created for later entries in the
ToX and if the heading is below the ToX then the node index in
SwUndoInsBookmark will not match the node index of the
CrossRefHeadingBookmark.

Thus SwHistoryBookmark::IsEqualBookmark() will cause the mark to be
skipped during Undo instead of deleted, and then it can cause trouble.

Work around that by having SwHistoryBookmark::IsEqualBookmark() not
check the position if it's a CrossRefHeadingBookmark.
