In helpdesk_mgmt v16, ``_compute_user_id`` automatically filled ``user_id`` with ``team_id.alias_user_id`` when the team was set and no user was assigned. This behaviour was removed in v18: the compute now only clears ``user_id`` when the assigned user is not a member of the selected team, without assigning anyone in its place. This commit restores equivalent behaviour using ``team_id.user_id`` (the Team Leader field) instead of ``alias_user_id``: - When ``team_id`` changes and the current ``user_id`` is not a member of the new team, the Team Leader is assigned automatically. - If the team has no leader configured, ``user_id`` is left unchanged to avoid creating unassigned tickets. - ``super()`` is not called: this is a full replacement of the v18 OCA behaviour, not an extension of it. Also updates README.rst to document the new auto-assignment behaviour.
