[FIX] resource: timezone end before assigning search_range

The end datetime is not timezoned in _adjust_to_calendar before defining the search_range and using the _get_closest_work_time method.
Since _get_closest_work_time will timezone the timestamp received to start searching, the search interval needs to refer to the same end timestamp to avoid erratic behaviors.
