[FIX] im_livechat : the default welcome message should come from the operator

Now the livechat supports identified users. So multiple user can be in the user_ids of a session. The author of the 'welcome message' is more difficult to identify. If portal user connected, the 'welcome message' author was this portal user instead of the operator. Required to pass operator id in the context to avoid the same mistake with an operator as 'client' and operator as real operator.
