Fix flaky multi_reference_table test (#6664) 

Sometimes in CI our multi_reference_table test fails like this:
```diff
 WHERE
 	colocated_table_test.value_2 = reference_table_test.value_2;
 LOG:  join order: [ "colocated_table_test" ][ reference join "reference_table_test" ]
  value_2
 ---------
-       1
        2
+       1
 (2 rows)
```

We forgot an ORDER BY in this test.
