MySQL supports DELETE with LIMIT and ORDER BY.

Before:

```
  Post Destroy (1.0ms)  DELETE FROM `posts` WHERE `posts`.`id` IN (SELECT `id` FROM (SELECT `posts`.`id` FROM `posts` WHERE `posts`.`author_id` = ? ORDER BY `posts`.`id` ASC LIMIT ?) __active_record_temp)  [["author_id", 1], ["LIMIT", 1]]
```

After:

```
  Post Destroy (0.4ms)  DELETE FROM `posts` WHERE `posts`.`author_id` = ? ORDER BY `posts`.`id` ASC LIMIT ?  [["author_id", 1], ["LIMIT", 1]]
```
