Fix deletion of a multi-day recurrent appointment
Fix deletion of a multi-day recurrent appointment

When the selected day in the calendar is a continuation day (not the first day)
of such an appointment, deleting the occurrence does not work. The reason is
that the selected day, and not the first day of the occurrence, is added as an
exception day.
