TO REPRODUCE

Steps to reproduce the behavior:
Telegram uses for group chats IDs with a minus at the beginning "tmchatid -123456789"
If you doublecheck at the console using "chatid" you will see the correct ID.
If you want to send a message to this chat it will fail.
The reason seems to be the following commit: 40ad4f7#diff-50b7d293806b164cb42a4bc8d06a84fbcacaf1803a6d30e42701f62367bdbdc4

Inside the commit the "chat_id" was changed from String to "uint_32_t".
Before this commit it was working also with chatIDs using a minus sign at the beginning.
Changing the "chat_id" from "uint_32_t" to "int_32_t" would fix this issue.
I have appended a diff.
