Corrected returned value of EvaluationMethods#evaluators_for method

Running @answer.evaluators_for(:answer_reputation) in console

invokes

    ReputationSystem::Evaluation Load (0.6ms)  SELECT "rs_evaluations".* FROM "rs_evaluations" WHERE "rs_evaluations"."target_id" = 131 AND "rs_evaluations"."target_type" = 'Answer' AND "rs_evaluations"."reputation_name" = 'answer_reputation'

It returns Evaluations not evaluators (in my case 'users') as opposed to the wiki.
