don't fail on export of ooo96040-2.odt to docx

If we want to close a cell of a table which encloses another table, then close
that enclosed table first.

These are pretty pathalogical old-school tables. For now assume this can only
occur when the row of the enclosed table is cleanly closed and assert if that
isn't the case.
