tdf#125300 extend AddParaSpacingToTableCells with line spacing
Now default compatibility mode AddParaSpacingToTableCells uses
not only paragraph bottom margin, but also proportional line
spacing before bottom cell border, as in MSO.

Note: disable testForcepoint76, because it fails again with
its fixed layout.

layout regressions are tricky. Can you check with different versions? (e.g Libo 3.3, 4.0, 5.0 and so on)

Hangs in 7.4+ from 6.4 as reported.
LO 6.3 opens 2 pages as attached, export from Linux.
LO 6.0 and below up to 4.0 opened 3 pages, 3rd one empty. 
LO 3.6 opened with 2 pages. 
LO 3.5 was wrong. 

Same if DOC resaved with MSO. MSO saved DOCX opens.
