Fix pg_prepared_statements.result_types for DML statements
Amendment to 84ad713cf85aeffee5dd39f62d49a1b9e34632da: Not all
prepared statements have a result descriptor. As currently coded,
this would crash when reading pg_prepared_statements. Make those
cases return null for result_types instead. Also add a test case for
it.
