xmpp: chatty does not show previously existing 1:1 chats in the message view.

When setting up an xmpp account in chatty, and opening chatty, the list of current 1:1 chats that a user might have from other clients is not shown in chatty. So the message list shows no xmpp 1:1 chats

So a xmpp user in chatty that sets up his xmpp account in chatty and wants to see all his 1:1 has to:

• press the + button, select: New message and the contact in question.

Chatty can see the persons contacts but from 1:1 existing chats but fails to fetch them, (the messages bellow been redacted of PII and are just some examples of a longer list):

But if we use pidgin on the same device using the same .purple folder, same dependencies, etc, pidgin can automatically can see the 1:1 chats and fetch them and present the: Buddies list no problem.
