Add support for named group chats

[sabogalc]

I have a group chat with two people that has a name and group chat photo. I used pypush to text these two people (made sure that the phone numbers and everything matched), and it made a new group chat rather than texting into the existing one.

I didn't consider the fact that pypush is a completely new instance of my messages so it may not have access to my message history, and hence the group chats. If this is indeed the case, I am okay with this just being closed (I'll await confirmation from the dev(s)).

Would still like to see this resolved for reducing friction between platforms

If the chat is named or has a photo, it'll create a new one. Otherwise, it should use the existing one as long as you match the participant's handles exactly. Pypush does not have access to your message history, although that is not necessary to preserve group chats.

How would one interact with names group chats then?

you can't with pypush atm, you need to send the n field in the payload with the chat name. Possible if you'd like to add tho.
