Remove count_method from test result module listox

- Too slow because it takes same time than the search_method.
- The count is made durring the search thank to LIMIT 1000;
- The search LIMIT 1000 takes same time than LIMIT 30;
- The search LIMIT 1000 stays in cache, so going to next page is almost instant.
