Adding hhvm to version list and allowed failures.
Cause RecurrenceIterator to respect the timezone of the event that is recurring.

The UNTIL value for the RRULE of an event is being parsed without a
timezone, thus all UNTIL values are in UTC timezone, even if that is not
what is indicated.

When the UNTIL value comes from a valid ICS feed that specifies a
timezone, but does not end with 'Z', the timezone of the event should
be used.

If the UNTIL value ends in "Z", it will still be interpreted as a UTC
value, and work the same way as current functionality.
