Incorrectly constructs URLs (two session IDs in the call)

I'm trying to use php-webdriver to communicate with Appium (which uses the WebDriver Wire Protocol) to test mobile apps. However, I get errors when I try to send requests, and it looks like the URLs are malformed.

Test code:

require_once '../vendor/element-34/php-webdriver/PHPWebDriver/__init__.php';
require_once '../vendor/element-34/php-webdriver/PHPWebDriver/WebDriverBy.php';                                    

class LoginTest extends PHPUnit_Framework_TestCase
{
  protected static $session;

  protected static $server_url   = 'http://localhost:4723/wd/hub';
  protected static $capabilities = array('app' => '/Users/lkung/Documents/iOS/AcceptanceTests/Test.app',
                                         'device' => 'iPhone Simulator',
                                         'version' => '6.1'
                                         );

  public static function setUpBeforeClass()
  {
    $driver = new PHPWebDriver_WebDriver(self::$server_url);
    self::$session = $driver->session('iphone', self::$capabilities);
    self::$session->implicitlyWait(15);
  }

  public static function tearDownAfterClass()
  {
    self::$session->close();
  }

  public function test()
  {
    $element = self::$session->element(PHPWebDriver_WebDriverBy::NAME,
                                       'Log in with Facebook');
    $element->click("");
  }
}

As seen in the logs, the implicit wait request and the element find request respond with the Responding to client that we did not find a valid resource error. The PHPUnit test fails due to Fatal error: Call to a member function click() on a non-object in /Users/lkung/Documents/iOS/AcceptanceTests/tests/test.php on line 30, since the element was not returned.

Looking at where the Appium request came from, Appium request initiated at /wd/hub/session/5b0446ac-c0ad-4441-9366-361c72783312/ 5b0446ac-c0ad-4441-9366-361c72783312 /timeouts, the session ID is present twice.

The error Appium throws for Android (using Selendroid) is slightly different (Proxied response received with status 500: undefined), but still looks like it has the session ID present twice. The PHPUnit test fails the same way - due to "click() on a non-object".
