[FIX] hr_holidays_attendance: delete overtime on leave cancelation

When a leave was canceled, the overtime record linked to it was not
deleted resulting in a wrong count of available overtimes.

Whatever the config of the time off type used to deduct extra-hours, its
total should be displayed in "hours" instead of "days" on the dashboard.
