Constructor for DrupalTestCase is reported to be the constructor for DrupalWebTestCase

The definition of the abstract class DrupalTestCase contains the following comment.

  /**
   * Constructor for DrupalWebTestCase.
   *
   * @param $test_id
   *   Tests with the same id are reported together.
   */
  public function __construct($test_id = NULL) {
    $this->testId = $test_id;
  }

It's clearly not correct, as the method is defined inside the class DrupalTestCase.
