tdf#161318 sw clearing break: fix this at section end HEADmaster

Regression from commit 19bca24486315cc35f873486e6a2dd18394d0614
(tdf#126287: docx import: use defered linebreak, 2022-02-07), the bugdoc
has a single paragraph in the first section, containing a clearing
break, which is lost. This leads to overlapping text as the text is
shifted up.

Seems the intention was to avoid a line break at the very end of the
document, as that can lead to an empty page with "next page" section
breaks, with non-clearing line breaks.

Fix the problem by only doing this for non-clearing line breaks: that
keeps the old use-case working, but the new, clearing line break then
shifts down the text, so no text overlap happens.

Switching from appendTextPortion() to HandleLineBreak() helps because
HandleLineBreak() does exactly appendTextPortion("\n") in the
non-clearing case, but knows about the stream stack's line break clear
status.
