ClientId in authentication url

[qdequippe]

Q	A
Version	3.16.2

Hi,

With the addition of $clientIdRequired to GetObject and to RestTool all authentication requests are prefixed the clientId.

This cause authentication errors and all requests failed.

http://localhost/v2.01/test/oauth/token

---

Steps to reproduce

1. Clone this repository
2. Add var_dump($this->_requestUrl) in MangoPay\Libraries\RestTool.php line 182 (see example below)
3. Run tests

# MangoPay\Libraries\RestTool.php line 182

private function BuildRequest($urlMethod, $pagination, $additionalUrlParams = null, $idempotencyKey = null)
{
    $urlTool = new UrlTool($this->_root);
    $restUrl = $urlTool->GetRestUrl($urlMethod, $this->_clientIdRequired, $pagination, $additionalUrlParams);
    $this->_requestUrl = $urlTool->GetFullUrl($restUrl);
    var_dump($this->_requestUrl);
    ....

Actual result

$ ./vendor/bin/phpunit

PHPUnit 9.5.26 by Sebastian Bergmann and contributors.

A workaround is to use version 3.14.1 of this sdk.
