tdf#134021 sw_redlinehide: fix crash if document contains only table

This sets the m_bTableDelLastNd flag in SwUndoDelete, so a SwTextNode is
created so that there's something in the document, and there are 2
problems with Undo:

1. ~SwIndexReg assert because there's a shell cursor on the text node;
could fix this with some PaMCorrAbs() but let's just call
DelFullPara() which takes care of that.
(this likely isn't possible in the !m_bTableDelLastNd case)

2. no frames are created in MakeFrames() because there's no node in the
document with layout frames, so delete it at the end.
(regression from 723728cd358693b8f4bc9d913541aa4479f2bd48)
