Fixes a situation where users who are part of the Attendances Officer (or Manager) group but
without access to private employee data would see the following error when trying to book time
off.
`ValueError: Invalid field 'last_check_in' on model 'hr.employee.public'`
Other instances of the same ValueError were observed by managers trying to approve employee leave
and employee expenses.
As per hr/models/hr_employee.py:22-26 fields not available on hr.employee.public should have
groups='hr.group_hr_user' and this was not the case in hr_attendance.
