Fix broken module namespacing in ActiveResource with Ruby 1.9 [#5699 state:resolved]

Following namespace use case was broken with Ruby 1.9:

  class Author < ActiveRecord::Base
    ...
  end

  module Api
    class Book < ActiveResouce::Base
    end
  end

Let's say XML contains <book><author><name>John</name></author>....

  Api::Book.first.author.class.to_s #=>
    Ruby 1.8.7: "Api::Book::Author" (namespaced, correct),
    Ruby 1.9: "Author" (toplevel, broken)
