calendar-server: Read timezone from the calendar, not its timezone cache

Browse Source 
The calendar's timezone cache holds only timezones already received
or added to the calendar, thus when asking it for a timezone for "the first
time", it returns NULL and a wrong timezone is used instead.
The get_timezone() does not do any I/O when the timezone is already cached
on the client side, thus it's fine to use it.

This could exhibit with non-recurring events, which use custom time zones,
in which case the event is shown in a wrong time.
