sw: WW8: fix crashtesting asserts on fdo45983-1.doc export to ODT

The problem is that a redline is created that contains the
CH_TXT_ATR_FIELDSTART but not the corresponding CH_TXT_ATR_FIELDEND:

(rr) p aRegion
$39 = SwPaM = {
point = SwPosition (node 443, offset 185),
mark = SwPosition (node 442, offset 0)
}
(rr) p aRegion.GetText()
$40 = "\aDie Studierendenvertiefen ihre Fertigkeit bei einfachen Handverletzungen, einen Befund zu stellen, Therapieziele zu formulieren, einen ergotherapeutischen Behandlungsplan zu erstellen und durchzuführen"

This is because commit d195a3e5f4ec5c616ae83f99d48f5d4eefe5f22e only
adapted one place in SwWW8ImplReader::End_Field() where a fieldmark is
inserted, but there's a second one ...
