[FIX] website: get visitor tz directly from cookie

Since tz is now (from 6eb4762fee20a158023d774a90e7ee90c2cacec5) added to the client cookie,
visitor timezone can directly be set when creating the visitor, using the
request.

Jstz can be removed as even for module in ENT that used this lib,
we can get the timezone using Intl lib instead.

This will also reduce the number of request made only to get visitor's
timezone.
