tdf#104714 bRemove paragraph: ignore frames in Headers/Footers

Empty paragraphs are removed in certain cases. If the previous
paragraph was in a frame, then this one shouldn't be removed
(unless that previous paragraph was in a header/footer).

Most of this patch is renaming the function to clarify that
it refers to the latest paragraph, not the very last one.

As noted in original tdf#75573, there may be other paragraph
containers that should also ignore their framed status - so
I've tried to set this up to make it easier to add those cases
when proof documents are found.
