[IMP] portal: add access token link in notification emails for customers

Purpose of this commit is to allow customer portal to have an access link
containing an access token. Portal mixin now override the default mail.thread
behavior when classifying recipients of a notification email in groups.

If the model has an access_token and a customer field correctly defined
the recipient that matches the customer will have an access link in its
notification email holding the access token. It will also contain an
auth signup token if it is enabled.
