Initialize linked list for recurrent items

When switching to the generic linked list implementation for recurring
events in 9fab248 (Use generic lists for recurring apointments and
events., 2011-04-16), no initialization routine for the list of
recurring events was added. Fix this and properly initialize the list on
startup.
