Fix `relation.exists?` with giving both `distinct` and `offset`
The `distinct` affects (reduces) rows of the result, so it is important
part when both `distinct` and `offset` are given.
Replacing SELECT clause to `1 AS one` and removing `distinct` and
`order` is just optimization for the `exists?`, we should not apply the
optimization for that case.
Fixes #35191.
