Fix memory leak by freeing linked lists in recurrence rules

Browse Source 
The function responsible for freeing a recurring appointment or event
did not free the linked lists contained in the `struct rpt` holding the
recurrence rules. This led to memory leaks if a user had recurring
appointments or events.

Found with ASAN.
