Так конструкция в запросе SELECT выполняется быстрее, т.к. именно по тому полю,
по которому был поиск идет подсчет, а когда поле подсчета указывается явно, как это сделано
сейчас (count(user_id)), то после выборки по условиям мускул начинает
ещё выковыривать user_id для каждой строки и только тогда считать по
этому полю.
