calendar-server: Get recurrence ID from occurrences

Browse Source 
We use the triplet of source ID, UID and recurrence ID to create
an ID to unambiguously identify an event, which we use to implement
hiding dismissed events from the calendar. However we currently
try to fetch the recurrence ID from the objects returned by
e_cal_client_get_object_list_sync(), which are always the primary
events with no recurrence ID. Instead, we need a recurrence ID
associated with each occurrence.
