Bug report

When creating a new recurring event in the Scheduler, the recurrenceRule does not contain WKST parameter (the first day of the week in the Scheduler). If you edit an existing recurring event, the WKST value is added to the recurrenceRule.

Reproduction of the problem

1. Open a Scheduler demo - https://demos.telerik.com/kendo-ui/scheduler/index.
2. Open the Network tab and create a new recurring event. The WKST value is missing.
3. Edit the same event - the WKST value will be added to the recurrenceRule.

Current behavior

The WKST value is not added to the recurrenceRule when creating a new recurring event.

Expected/desired behavior

The WKST value should be added when creating a recurring event.
