Sets whether calendar sources within the collection should be enabled.
An ECollectionBackend running within the registry D-Bus service will automatically synchronize any calendar sources it
maintains with the calendar_enabled property.
Calling this function from a registry service client has no effect until the change is submitted to the registry service through write, but there should rarely be any need for clients to call this.
