IndexOutOfRangeException when constructing RecurrencePattern

[derekantrican]

The following throws an IndexOutOfRangeException:

new RecurrencePattern("RRULE:FREQ=WEEKLY;BYDAY=MO;UNTIL=20220708T110000Z;INTERVAL=2;");

After a small amount of testing (which is by no means conclusive), I think the issue is with the trailing semicolon. Removing that does not throw an excepiton.

Can you confirm?
