lilia 0741c74618 Don't recreate views unnecessarily
Let ConversationListItemView save a reference to its corresponding
ConversationView. This lets it render or delegate/undelegate events
when opening and closing a conversation.

Similarly for ConversationView itself, which contains a MessageListView.
