TypeError throw when try to edit / delete schedule in Task

[YoiDuki]

Describe the bug

Hi guys, when i try to add some my own function before edit/delete schedule events, it throw below exception:

weekView.js:278 Uncaught TypeError: Cannot read property 'fire' of undefined
    at onDeleteSchedule (weekView.js:278)
    at ScheduleDetailPopup.CustomEvents.invoke (tui-code-snippet.js:3230)
    at ScheduleDetailPopup.CustomEvents.fire (tui-code-snippet.js:3185)
    at ScheduleDetailPopup._onClickDeleteSchedule (scheduleDetailPopup.js:110)
    at ScheduleDetailPopup._onClick (scheduleDetailPopup.js:81)
    at HTMLDivElement.handler (domevent.js:54)

It only appears when i set scheduleView: false or scheduleView: ['allday']. It only appears in day/week view, won't appear in month view. So i think that there must be something wrong in time view. Then i look into the callstack, when it ran into function onDeleteSchedule:

onDeleteSchedule = function(eventData) {
    (eventData.isAllDay) {
        weekView.handler.creation.allday.fire('beforeDeleteSchedule', eventData);
    } else {
         weekView.handler.creation.time.fire('beforeDeleteSchedule', eventData);
    }
};

The param of function is not a Schedule object, so it doesn't have a isAllDay prop, then it jump into the else block. But as i set time view as false before, the time object is undefined, so the issue happened,

To Reproduce

Steps to reproduce the behavior:

1. Create a calendar sample.
2. set scheduleView as false.
3. create a schedule, which category is task.
4. try to edit the schedul or delete it on screen.

Expected behavior

No exception happened and the listener event triggered correctly.
