tiennm99 3a12615ef5 fix(reply): forward message_thread_id so replies stay in the same forum topic
Telegram routes outgoing messages with no message_thread_id to a forum
supergroup's General topic. Commands sent in a topic were being answered
in General. chathelper.Reply / ReplyHTML now take *models.Message and
forward both ChatID and MessageThreadID; help.go SendMessage and
loldle trySendSticker do the same. Adds regression tests asserting the
field is forwarded for forum topics and omitted for private/regular groups.
