* In new data model it means, get X questions from every lesson in the course, except
* 1) immediate lessons-childs of the course and
* 2) lessons, contains other lessons (because, in old data model chapters doesn't contains questions)
*
* 'H' - all questions from the selected chapter (recursive) in the course
* This case must be ignored, because converter to new data model updates 'H' to 'R', but in case
* when chapter is not exists updates didn't become. So QUESTIONS_FROM stayed in 'H' value. And it means,
* that there is no chapter exists with QUESTIONS_FROM_ID, so we can't do work. And we should just
* ignore, for backward compatibility (so, don't throw an error).
* 'S' - all questions from the selected lesson (unilesson_id in QUESTIONS_FROM_ID)
* 'A' - all questions of the course (nothing interesting in QUESTIONS_FROM_ID)
*
* new values:
* 'R' - all questions from the tree with root at selected lesson (include questions of selected lesson)
