1.3.8-beta.9: отписка от канала видна по участникам — статус канала в CHAT_INFO его собственный (BFM после отписки: CHANNEL, ACTIVE), подписка = аккаунт среди participants (как isViewerParticipant в MAX web, без него нет «Отписаться»); нет participants или своего id — не знаем, догружаем как раньше; в логе: тип, статус, число участников и есть ли среди них аккаунт
