public function CourseObjectBook::save in Course 8.2

Same name and namespace in other branches

1. 8.3 modules/course_book/src/Plugin/course/CourseObject/CourseObjectBook.php \Drupal\course_book\Plugin\course\CourseObject\CourseObjectBook::save()
2. 3.x modules/course_book/src/Plugin/course/CourseObject/CourseObjectBook.php \Drupal\course_book\Plugin\course\CourseObject\CourseObjectBook::save()

Override of CourseObjectNode::save()

We have to remove the stock "view" content access permissions on Books, if node_access_book is enabled. Otherwise, users outside of the course can still access child book pages of a private book parent.
