    tdf#155685 sw: fix another ExtendedSelectAll Redo crash w table at end
    
    This can be reproduced with a table containing in the last cell a
    paragraph followed by a table, then ExtendedSelectAll in the cell and
    delete.
    
    On Redo of the SwUndoDelete:
    
      warn:legacy.osl:326138:326138:sw/source/core/frmedt/tblsel.cxx:1775: 
MakeSelUnions with pStart or pEnd not in CellFrame
      In function:
        const_reference std::vector<SwTableBox *>::operator[](size_type) const
        [_Tp = SwTableBox *, _Allocator = std::allocator<SwTableBox *>]
      Error: attempt to subscript container with out-of-bounds index 0, but
      container only holds 0 elements.
    
    The problem is that DelTable() calls PaMCorrAbs() with a target that is
    outside of the outer table, so the SwEditShell::DeleteSel() rPam has one
    end in the last table cell and other end outside the table.
