[FIX] hr_holidays: leave type in hours in new leave request

When a new request of leave is created, some fields are computed to
calculate if it's possible or not, to take the leave
(virtual_remaining_leaves, leaves_taken, remaining_leaves and
max_leaves).

These fields are computed using the fields :
allocation : hr_leave_allocation.number_of_days.
and request : hr_leave.number_of_days.

When a leave type is in hours, both of these fields are calculated
differently:
allocation: The allocation field is calculated dividing the number of
hours registered by the user per the average hour per working day.
(https://github.com/odoo/odoo/blob/d809b476819968837b61bdd78fbf101caac73adc/addons/hr_holidays/models/hr_leave_allocation.py#L236)
request : The request field is calculated by finding the real number of
requested days.
(https://github.com/odoo/odoo/blob/d809b476819968837b61bdd78fbf101caac73adc/addons/hr_holidays/models/hr_leave.py#L360)
If in the company each day have different working hour, then the number
of days calculated with the average hours didn't represent the real
number of days that the employee can take. This issue can avoid the
employee to take a leave even if he has the correct number of hours to
take it.

Now, the fields (virtual_remaining_leaves, leaves_taken,
remaining_leaves and max_leaves) are calculated using either the days
fields or the hours fields depending on the leave type.
