tdf#115861 DOCX import: avoid last-paragraph removal when discarding footer

Discarding header/footer is necessary when the document or section
settings request to ignore first or even headers/footers. In the bugdoc
case settings.xml didn't opt-in for different even/odd footers, but
there was an even footer to be ignored.

Handle this state at two more places, so we don't end up in a situation
where we ignore the footer but not its "remove last (empty) paragraph at
the end of the footer" action.

Also make the debug dumper for text ranges more robust to have a working
token dump when we try to get the string for a table.
