Re-architecture of the chat structure

I re-wrote a good part of the chat with:

A new store directly in the context, this way messages are shared and there is no incoherence between the different views (had a bug of "refresh" because of this)
Remove most of concepts of Conversation only using the peerAddress + messages to keep it simple
- Might create an issue later if we want to support group but I don't believe Conversation is compatible with groups anyway
Activate stream on all messages from the provider
Created a bunch of new simplified hooks to replace some heavy hooks we had that were doing all in one
- useMessages that get the messages from the store
- useFetchMessageFetcher that fetches the messages
- useSendMessage that sends a message
- useConversations that get all the conversations from the store
- useFetchConversations that fetches the conversations
Disable the form when submitting
Display messages from the store first and load in the background (changed the loader)
Move some logic to helpers
