[FIX] mail: odoobot message remains unread

Before this commit, messages sent by OdooBot would remain unread.
1. Log in as demo user
2. Open OdooBot chat, remains unread

This happens because the `_set_last_seen_message` method called by the
OdooBot reply logic sets the message as seen for the user. This results
in the message being marked as read before it is received, preventing
it to be marked as read by the client.
This commit fixes the issue by preventing the message to be mark as
read if the author is not the current user.

Also added missing `message_unread_counter_bus_id` from
`assignedDefined` that would prevent it to be set by record inserts.
