Implement Request::getBasicCredentials for http basic auth testing

`getBasicCredentials` method is implemented in Nette\Http\Request, but it's not part of IRequest interface, so it was missing in this Codeception\Http\Request implementation. With this change we can use `$this->tester->amHttpAuthenticated()`.
