ActiveRecord Relation size mismatch on last page when not loaded

[hallelujah]

This can be added to spec/finders/active_record_spec.rb

  it 'returns correct `size` for last page' do
    users = User.paginate(:page => 3, :per_page => 5)
    users.total_entries.should == 13
    users.total_pages.should == 3

    users.size.should == 3
  end

The test is failing:

bundle exec rspec spec/finders/active_record_spec.rb:420                                                                                    [2.3]
