tdf#91083 - .doc: emulate table kept-with-next not splitting

An .odt table can “keep with next paragraph”.  This means that the entire
table may shift to the next page and all the rows will keep together as
the table attempts to stay on the same page as the following paragraph.
There is no “keep with next” property for .doc tables, but each row CAN
be kept with the following one.  When exporting an .odt file to .doc,
setting each row like this will keep the text flow similar to the
original .odt's layout.

This commit only hinders the table from splitting - it does not actually
affect keeping with the following paragraph.

This functionality already exists in the code, but was broken
by a variable that “changed meaning” almost as soon as the
functionality was introduced.

A followup commit will deal with "full page" situations when the kept
sections are too large to fit on a single page and so the table should
split instead of start a new page. The only situation that can't be
handled nicely is a single table kept-with-next that spans more than
one page. Such tables ought not be marked as keep-with-next anyway.
