RST reader: Don't create empty definition list for metadata field lists.
Previously a field list consisting only of metadata fields (author,
title, date) would be parsed as an empty DefinitionList, which is not
legal in LaTeX and not needed in any format. This patch fixes the
problem, which I learned of from
http://stackoverflow.com/questions/12762767/modify-variable-in-rst-with-pandoc.
