tdf#103931 writerfilter breaktype: same for implicit and explicit

MSWord normally does NOT specify "nextPage" for the sectionBreak,
since that is the default type. That is imported as BreakType == -1.
However, Writer ALWAYS exports the section type name, which of
course is imported explicitly.
**There is an import hack that treats the very first -1 section as
continuous IF there are columns**. Since Writer explicitly defines
the section type, these documents import differently.

When Writer round-trips these types of files, they get totally
messed up in Writer, although they look fine in Word. So, treat
both implicit and explicit nextPage identically for
bTreatAsContinuous during import.

Another unit test demonstrated that headers/footers are lost when
treating as continuous, so preventing that situation now also.

This fix allows several import-only unit tests to round-trip.
