Discussion association

A discussion can be directly associated to a message in case of a reply so the participants will not be editable.

Reply or Compose a message

For a new message (compose button), we let the user choose the recipients and save it as is. The user can change the recipients with no restrictions. The discussion_id is calculated by the backend each time the draft is saved. The parent_id is undefined if it is a new draft (compose).

In case of a reply, the parent_id is set by the client. And the backend accepts a discussion_id and participants but it will recalc the discussion_id and the participants each time the reply is saved.
