"all_day" : 1 seems to have no effect on create new calendar entry

[ZacKnaus]

Following the examples here: https://marketplace.humhub.com/module/calendar/docs/swagger/calendar.html#tag/Calendar-entry/paths/~1calendar~1container~1%7Bid%7D/post , the all_day attribute doesn't seem to have any effect when new calendar events are submitted. The server confirms receipt, sets the event on the calendar according to the submitted dates/times but the response from the server shows a 0 for all_day when a 1 is submitted. I've tried adjusting the dates/times to match other examples the above page but nothing seems to allow me to create new calendar events as all_day events.

POSTed to: https://{domain}/api/v1/calendar/container/{sleep_calendar}

example JSON that won't create an all-day event:

   {
      "CalendarEntry": {
        "title": "Sleep - 8h 40m (EXCELLENT)",
        "description": "",
        "color": "#1AA7EC",
        "all_day": 1
      },
      "CalendarEntryForm": {
        "start_date": "2023-02-10",
        "start_time": "18:00:00",
        "end_date": "2023-02-11",
        "end_time": "05:59:00",
        "timeZone": "America/New_York"
      },
      "content": {
        "topics": [
          {
            "name": "Sleep"
          }
        ]
      }
    }

@yurabakhtin Can you please review this? Especially humhub/rest#113

[yurabakhtin]

@luke- I confirm the changes in all 3 PRs. No need to keep the method prepareRequestParams completely, because it forces all_day to 0 when start or end dates are passed, that is strange, also the verifying from the method works well from calendar and task models side.
