Before this commit, when a record is in draft, the chatter message "Creating a new record..." shown no author. The intended showing is to display current user as author of this message. Persona model requires `id` and `type`, the latter to determine whether the persona is a guest or partner. Only the id of current user was provided, so it was not enough to determine the appropriate `Persona`. closes odoo/odoo#144864 Signed-off-by: Sébastien Theys (seb) <seb@odoo.com>
