validate_inclusion_of with_message doesn't actually check the message

[bgentry]

Given the following validation:

class MyModel < ActiveRecord::Base
  include ActiveModel::Validations

  validates :letter, presence: true, inclusion: { in: %w{A B C}, message: "must be A B C" }
end

this test will pass, even though the message doesn't match:

require 'rails_helper'

RSpec.describe MyModel, :type => :model do
  it { should validate_inclusion_of(:letter).in_array(%w{A B C}).with_message("BROKEN TEST") }
end

Thanks for reporting this, I will take a closer look soon.
