Fix memory leak in res_calendar_icalendar

Browse Source 
The ICalendar module had a systemic memory leak on each fetch of data from
the ICalendar source. The previous fetched data was not being properly
disposed. This patch makes it so that before each fetch of data, we dispose
of the previously fetched data.

(closes issue ASTERISK-21012)
