fdo#70143: fix SwDoc::ReplaceRangeImpl()

Fix fdo#70143 by reporting swaping of positions

(regression from 6b08fe833186a04f9aef698a540d3a7493ac4519,
which changed SwUndoReplace::Impl::SetEnd to use the wrongly set end
position in rPam)

Change-Id: I14c6f58bc5c1418c69eb565d42f1829856eed58c
(cherry picked from commit 9685d20f2a0526a4c454cea1bd947eccbaeefa84)

Fixes regex replace of "$" with nothing (to delete line
breaks).
