[FIX] mail: send notification mail with right access link when using mail.thread

PURPOSE

Notification may be sent using a generic mail.thread record, notably when
sending user notifications. In that case links to view document are
incorrect.

HOW TO REPRODUCE

Issue

    - Install "Approvals"
    - Submit new approval with you as "Request Owner"
    - Click on "View Approval Request" in your mailbox

    The link redirects to a 505 error

Cause

    The model is not the correct one and the res_id is undefined

Solution

    Specify the model and the res_id to _notify_get_action_link
    when creating the link with kwargs

SPECIFICATIONS

Propagate message value through various notification sub methods. That way
we can rely on them if model seems void.

Also limit values given as URL parameters to some white listed values.
