[FIX] hr_holidays_attendance: correct date overtime attendances

Issue:
------
The `date` field of the `hr.attendance.overtime` model
records is not the date of the related leave.

Cause:
------
We use: `fields.Date.today()` instead of the leave field `date_from`.

Solution:
---------
Use `date_from` field of `leave`.
