[FIX] hr_*: access rights issues when changing employee's user

- When changing the user of a `hr.employee` record, access rights errors
  could be triggered.

  Those errors are triggered when a record (for example a leave) is
  linked to this employee and the current user has limited write
  accesses by record rules on this record.
