Remove from the DbLogController class the properties already defined from the parent class

The DbLogController class defines the following properties.

  /**
   * The module handler service.
   *
   * @var \Drupal\Core\Extension\ModuleHandlerInterface
   */
  protected $moduleHandler;

  /**
   * The form builder service.
   *
   * @var \Drupal\Core\Form\FormBuilderInterface
   */
  protected $formBuilder;

Those properties have been already defined from the parent class, ControllerBase and they should be removed from the DbLogController class.
