Address random `test_or_with_bind_params` failures

Reported at https://travis-ci.org/rails/rails/jobs/274370258

- `Post.find([1, 2])` generates this query below:
```sql
SELECT "posts".* FROM "posts" WHERE "posts"."id" IN ($1, $2)  [["id", 1], ["id", 2]]
```

- `Post.where(id: 1).or(Post.where(id: 2)).to_a` generates this query below:
```sql
SELECT "posts".* FROM "posts" WHERE ("posts"."id" = $1 OR "posts"."id" = $2)  [["id", 1], ["id", 2]]
```

Most of the time these two queries return the same result but the order of records are not guaranteed
from SQL point of view then added `sort` before comparing them.
