tdf#128739 sw: delete fieldmarks if exactly selected ...

... in SwUndoSaveContent::DelContentIndex().

The problem is that the fieldmark survives but its dummy characters are
all deleted; this will eventually lead to unhappiness in Undo.

Another issue is that SwHistoryBookmark doesn't know about dummy
characters, so use the SwHistory*Fieldmark instead.

This still doesn't work completely because SwUndoDelete::RedoImpl() is
quite borked.
