Fix leaving private chats
Chat history of private chats is cleared successfully, but somehow leaving them does not work...
deleteChatHistory
is used and should also remove the chat from the list if you tell it to do so:

Do we have to delete the chat manually from model? I think I tried that too, but maybe I've done it wrong.
