tdf#146081 sw: Fix inconsistent prop line spacing
Previously, when using proportional line spacing <100%, Writer applied
inconsistent height and ascent adjustments to the first and non-first
lines of paragraphs. This caused Writer to render text at inconsistent
vertical offsets.
Height and ascent adjustments are now consistent.
