refactor!: cleaner message history sync

This is a breaking change,
1. three events (chats.set, contacts.set, messages.set) are now just one `messaging-history.set` event
2. no need to debounce for app state sync
3. added a new "conditional" chat update to allow for correct app state sync despite not having the chat available on hand
