    gtd-task: Fix leak of ECalComponentDateTime
    
    As the document states on e_cal_component_get_due:
    
     "Return value for the due date/time. This should be freed with the
      e_cal_component_free_datetime() function."
    
    3,168 bytes in 66 blocks are definitely lost in loss record 15,883 of 16,044
