* Check if a group chat is still unpromoted.

* until the first call to dc_send_text_msg() or another sending function.
*
* With unpromoted chats, members can be added
* and settings can be modified without the need of special status messages being sent.
*
* While the core takes care of the unpromoted state on its own,
* checking the state from the UI side may be useful to decide whether a hint as
* "Send the first message to allow others to reply within the group"
* should be shown to the user or not.
