CalendarEventsList API in some cases returns wrong time for cancelled events

[Manyasha]

When a guest user is removed from a meeting by the owner, or the owner reschedules the recurring event to a different day, the cancellation event for the guest received through the API contains the wrong time in the past.

For example:

User A created an event and added User B to the participant list. After that User A removes User B from this event.

Using the Events:list API (https://developers.google.com/calendar/api/v3/reference/events/list) through the Node.js client library or directly in the Google APIs Explorer with params "showDeleted" = true and "singleEvents" = true, we get the following:

(Requests run against user B's calendar.)
