[FIX] resource: Find intervals in the resource timezone

With a user with timezone "Europe/Brussels", add a
slot on the gantt view where the preceding day is a working day.
The default starting time will be the previous day.
Reason: the default starting time is midnight, adjusted to
the closest attendance interval in the employee's calendar.
However, midnight in "Europe/Brussels" is actually 10pm UTC
the previous day.
The method adjusting the datetime to the closest attendance only
checks within the corresponding day.

Two ways to fix this:
1) the business code calling `_adjust_to_calendar` should
   timezone the datetimes itself. To avoid similar bugs in the future,
   the method should be modified to only accept timezoned datetimes.

2) Change `_adjust_to_calendar` to convert datetimes it was given
   to the resource's timezone and consider the dates in those converted
   datetimes.

Option 2 is chosen because it seems to take care of the problem at a lower
level which allows the business code to not think about those timezone details.
While this is technically an API change (in a stable release), the method was
introduced recently by b058ca1 as a fix for an already broken method.
