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.
