Before this commit, when the user is just a planning user without any
access to the Employees and Contracts apps. A traceback is occurred
saying the user cannot access to the `hr.contract` model.
This commit adds a `sudo` in `_get_valid_work_interval` method to get
the resource calendar of resources within a interval (the one of the
gantt view). This sudo does not give any recordset in sudo since the
`_get_calendars_validity_within_period` method return a dict with
resource_id as keys and the intervals valid according the resource
calendar for the interval.
