dont decorate nil class

[bekicot]

I create a custom load strategy

module Draper
  module QueryMethods
    module LoadStrategy
      class ActiveRecordWithKlass
        def allowed?(method)
          @allowed ||=
            ::ActiveRecord::Relation::VALUE_METHODS +
            [:klass, :reflect_on_association]
          @allowed.include? method
        end
      end
    end
  end
end

It tries to decorate nil class in lib/draper/query_methods.rb:7
because

`scope`.reflect_on_association

is returning nil

It should return the value as is
