When a message is posted, the server sends a `mail.record/insert` notification to update the related channel pin state. In order to recognize the thread, the client needs its id and its model. Currently, only the id is passed so the thread pin state is not updated. This PR adds the model to the notification. closes odoo/odoo#155150 Signed-off-by: Sébastien Theys (seb) <seb@odoo.com>
