tdf#141613 sw: avoid possible crash when undoing header creation
Move the ClearRedo() call to the very end of the undo process in order to avoid heap use after free.
We still need to call ClearRedo() because there's no mechanism in place to Redo a header/footer change.
Regression from commit 65e52cb61d74b0c71b45b63b2da131bc6b621104
"tdf#141613 sw: fix crash at header/footer undo".
