Use PurpleProtocolConversation if it's available when sending a message.
Review Request #2614 — Created Sept. 11, 2023 and submitted — Latest diff uploaded
Eventually PurpleConversation.send will be going away, but for now we'll use the PurpleProtocolConversation interface if it is available to send messages rather than the PurpleProtocolChat and PurpleProtocolIM interfaces.
Send message with the IRCv3 protocol updates from /r/2615 without issue. Also sent messages via xmpp to an im and a chat.
