[FIX] hr_holidays: make _onchange_request_parameters handle timezones

At the end it constructs date_{from,to} (Datetime) by combining:

- request_date_{from,to} (Date) local to the user
- UTC time from date_{from,to} (extracted using time() into hour_{from,to})

This doesn't work in all cases, e.g.:

A leave in US/Pacific for one day (with request_unit_custom = True):
- request_date_from: 1st of Jan
- request_date_to:   1st of Jan
- hour_from:         15:00 (7:00 local)
- hour_to:           03:00 (19:00 local) <-- this happens on the 2nd of Jan in UTC

Before this patch it resulted in:
date_from: 1st of Jan 15:00
date_to:   1st of Jan 03:00

The correct value for date_to is:
date_to:   2nd of Jan 03:00

_adjust_date_based_on_tz takes care of adjusting the date based on the
hour and the user's timezone.
