See also bug #70693

Activesyncd is losing the "nth" attribute for monthly repeating BYDAY events.

The following EAS data:

            <Recurrence xmlns="Calendar:">
              <Recurrence_Type>3</Recurrence_Type>
              <Recurrence_Interval>1</Recurrence_Interval>
              <Recurrence_WeekOfMonth>1</Recurrence_WeekOfMonth>
              <Recurrence_DayOfWeek>16</Recurrence_DayOfWeek>
            </Recurrence>

is turned into the following RRULE:

RRULE:FREQ=MONTHLY;BYDAY=TH

which should be:

RRULE:FREQ=MONTHLY;BYDAY=1TH

This is obviously related to bug #70693.  Until I investigate further, I don't
know if this is caused by the same underlying problem as that bug, is a
deliberate attempt to avoid triggering that bug or is a separate bug.  Even if
this is separate, bug #70693 may still prevent the corrected event from being
synchronised.

As events with recurrence like "first Monday of the month" are very common, it
would be nice to fix this.
