Fix definition specs not to be couple with Json::Reader
user
```ruby
describe Swarker::Definition do
  let(:swagger_definition) do
    YAML.load_file(File.expand_path('../../fixtures/definitions/swagger.json.yml', __FILE__))
  end
  let(:lurker_definition) do
    YAML.load_file(File.expand_path('../../fixtures/definitions/lurker.json.yml', __FILE__))
  end

  subject { Swarker::Definition.new(:user, lurker_definition) }

  it '#object has no required data' do
    expect(subject.object['required']).to be_nil
  end

  it '#object convert required attributes' do
    expect(subject.object['properties']['id']['required']).to be_truthy
  end

  it 'converts definition' do
