tdf#130680 sw_redlinehide: fix crash in SwUndoDelete
The problem is that the code that adjusts pLastNode in
SwContentNode::DelFrames() assumes that the nodes are deleted forward
but MoveNode() runs backward so the only solution is to put pLastNode
temporarily onto some node without checking if it has been fully
deleted, while skipping over tables and sections.
At the end of MoveNode() it must be on a valid (not fully deleted) node
again.
(regression from b86ff2c6a88aa41379e74f11e8ec8497ff85ffd0)
