tdf#126723 writerfilter::finishParagraph - me, not previous

In LO 6.2 commit 480ac84f2f5049fb4337b36f12fd6796e005761b
the existing m_xPreviousParagraph was conveniently used to
apply the changed properties. I never did like that choice,
but despite looking at it, I failed to see that it is set
in an inside loop, which means that it was NOT NECESSARILY
reset to the current paragaph. So I'm happy to have proof
that we should not use m_xPreviousParagraph.
