Only merge scopes with zero arity in has_many through
with dynamic conditions.
Fixes #16128
This bug was introduced in https://github.com/rails/rails/commit/c35e438620f2d56562251571377995359546393d
so it's present from 4.1.2-rc1 and after.
https://github.com/rails/rails/commit/c35e438620f2d56562251571377995359546393d
merges any relation scopes passed as proc objects to the relation,
but does *not* take into account the arity of the lambda.
To reproduce: https://gist.github.com/Agis-/5f1f0d664d2cd08dfb9b
