Subject: [PATCH] Set the viewer timezone properly on Calendar event
 RecurrenceSet objects

Summary: Ref T11801. In some cases, this could lead to us failing to generate the first recurrence in a series.

Test Plan: Imported `weekly.ics` (from D16974) and saw an event correctly occur on Aug 18, with my local timezone set to "America/Los_Angeles".
