RemoteWebDriver ignores old configuration properties

public void simpleWebdriverTest(@Drone RemoteWebDriver webdriver) {
        webdriver.get(contextPath.toString());

        webdriver.findElement(By.id("name")).sendKeys("Samuel");
        webdriver.findElement(By.id("email")).sendKeys("samuel@vimes.dw");
        webdriver.findElement(By.id("phoneNumber")).sendKeys("1234567890");
        webdriver.findElement(By.id("register")).submit();

        // FIXME with Graphene, you can wait for a request
        Assert.assertTrue(true);
    }
