title: OkHttp3 logging interceptor does not log cookies
body: <p>I'm using OkHttp 3 (with retrofit2) and I'm trying to get both cookies and logging to work. The problem is the log shows everything but not the cookies. I have captured the HTTP traffic and the cookie ARE being sent, they are just not logged. I tried debugging the logging interceptor, and indeed, the request appears to have no cookies (although it does have other custom headers) when it reaches the <code>intercept()</code> call. Any ideas what am I doing wrong?</p>
  
  <pre><code>    final Gson gson = new GsonBuilder()
              .setDateFormat(JSON_DATE_FORMAT)
              .create();
  
      HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
      logging.setLevel(HttpLoggingInterceptor.Level.BODY);
      CookieManager cookieManager = new CookieManager();
      cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
  
      OkHttpClient.Builder okClientBuilder = new OkHttpClient.Builder()
          .addInterceptor(new Interceptor() {
              @Override
              public Response intercept(Chain chain) throws IOException {
                  Request request = chain
                          .request()
                          .newBuilder()
                          .addHeader("custom-header", Utils.getRandomUUIDForHeader())
                          .build();
                  return chain.proceed(request);
              }
          })
          .cookieJar(new JavaNetCookieJar(cookieManager))
          .addInterceptor(logging);
  
      if (mock) {
          okClientBuilder.addInterceptor(new MockApiInterceptor(context));
      }
  
      return new Retrofit
              .Builder()
              .baseUrl(serverURL)
              .client(okClientBuilder.build())
              .addConverterFactory(ScalarsConverterFactory.create())
              .addConverterFactory(GsonConverterFactory.create(gson))
              .build()
              .create(DefaultApi.class);
