tdf#131684 sw_redlinehide: fix SwUndoDelete for entire doc in section

The problem is that in SwUndoDelete::UndoImpl(), at the start there is
only one content node with a frame in the layout, and there is a special
case with m_nReplaceDummy being set so this SwTextFrame gets deleted by
the MoveNodes() call in line 969 that moves it into the newly inserted
section.

As a result of that, MakeFrames() won't do anything because it can't
find an existing frame in the same section.

In this case, MoveNodes() should leave the frame alone, as it is beyond
the end of the deletion and excluded from MakeFrames() - if it wasn't
merged before then it doesn't need action, if it was merged before (in a
different document maybe) the RecreateStartTextFrames() ought to fix it.

(regression from 723728cd358693b8f4bc9d913541aa4479f2bd48
 which disabled immediate creation of frames in Copy_())
