[BUG]: allDay property is set to true for non-all-day events

[Programie]

Describe the bug
I have some events which don't have an end-date (i.e. the end date is the same as the start date). Every calendar application is correctly handling that event as a non-all-day event. But in case of this Node-RED module, those events are flagged as all-day events (i.e. allDay of those events is set to true).

To Reproduce
Steps to reproduce the behavior:

1. Create an event on your calendar server and select the same date/time for start date and end date
2. Connect a trigger to the "upcoming" node and connect that node to a debug node
3. Trigger the node
4. The data shown in the debug node includes allDay: true for the previously created non-all-day event

Expected behavior
The event should have allDay: false in case the event is not an all-day event.

As this is still an issue, I've looked for a workaround and found a way to check whether the event is a non-all-day event while the start and end times are the same.

It's quite easy but I didn't saw that before: Just check whether durationSeconds is zero. If that's the case, the event should not be an all-day event. Checking whether eventStart and eventEnd are the same should also work, but I guess it could have different values if eventStart and eventEnd use different time zones.
