odoo/odoo#64626 attempt at improving sms.template rules seems quite broken
* do not restrict system group to calendar.event: this makes no sense.
With this fix admins can now only use templates being linked to calendar
event if calendar_sms is installed which is not really smart. Not sure
what was the exact original purpose;
* ir.rule in hr_presence has no use on hr.manager group if they do not
have any access through access rules. Indeed they are currently
restricted to read access as all standard internal users;
