testing: be strict about DTSTART + EXDATE matching

Although IMHO it is not explicitly specified by iCalendar 2.0, it is
good practice and in fact expected by at least two servers (Apple
Calendar Server, Oracle Communication Calendar Server) that DTSTART
and EXDATE are using the same time format. If DTSTART is UTC, so
should be EXDATE, same for TZID and DATE-TIME/DATE.
