[11.x] Fix HasManyThrough::one()

[staudenmeir]

HasManyThrough::one() doesn't actually work because it duplicates the JOIN clause and breaks the query:

select "articles".*, "users"."team_id" as "laravel_through_key"
from "articles"
         inner join "users" on "users"."id" = "articles"."user_id"
         inner join "users" on "users"."id" = "articles"."user_id"
where "users"."team_id" = 1
order by "created_at" desc
limit 1

We need to remove it before HasOneThrough adds it again.
