Subject: [PATCH 079/109] fdo#71429: sw: fix crashes when changing header first
 sharing

Copy some nutso code in SwUndoPageDesc::ExchangeContentNodes() to
work on the un-shared First header/footer too, which apparently avoids
the crash.  It's not like Undo of header/footer isn't already a
house of cards anyway.
