Review comment:
       If we call `this.enableSendingOldValues()` then `enableSendingOldValues` is not called on the `KTableFilter` instance. Whereas calling `kTable.enableSendingOldValues()` does call `KTableFilter.enableSendingOldValues()`.
   
   The call to `KTableFilter.enableSendingOldValues()` is needed to ensure the filter expects the old values.
