Remove PurpleChatConversation usage from Pidgin
Review Request #3105 — Created April 13, 2024 and submitted — Latest diff uploaded
PurpleChatConversation is on its way out, but this is blocking it's removal. The invite dialog was also removed as it will need to be updated to be aware of adding users to existing conversations that could be group dms or even channels.
Had the turtles run this on top of the branch from r/3106
