ECA EXTRA FIELD - Empty content view

The link to the MR in entity_extra_field is really helpful, thanks.

There is a difference in handling, though. ECA's render view action just uses views_embed_view to receive a renderable array. But that doesn't allow testing for an empty result set in the view.

We would have to re-implement \Drupal\eca_render\Plugin\Action\Views::doBuild entirely by using something like this:

    $view = Views::getView($view_name);
    $view->setDisplay($this->getViewDisplay());
    $view->setArguments($this->getViewArguments($entity));

    // Test for empty result set here.

    return $view->buildRenderable(
      $this->getViewDisplay(),
      $this->getViewArguments($entity)
