Bug report

PivotGrid has the Include Fields option. When a child field is removed from the pop-up treeview, it is not possible to add it anew since the checkbox is not preserving its state.

Reproduction of the problem

Open the dojo:
https://dojo.telerik.com/@sspasova/oBAloXAp

And follow these steps:

1. Click on the callType menu button
2. Select Include Fields...
3. Expand and Uncheck Low Credit Calls
4. Click OK
5. The field is successfully removed
6. Try the same operations to add it back
7. The Low Credit Calls checkbox is already checked ❌

Scenario 2:

1. Open the Demos - https://demos.telerik.com/kendo-ui/pivotgrid/remote-flat-data-binding

2. Click on on the 'Include Fields' option for the Countries. Uncheck some of the countries, for example 'Mexico' and 'UK'.

3. Click the OK button.

Current behavior: All countries are selected again and can not be unchecked.

Expected behavior: The filter should be persisted and previously unchecked countries should remain unchecked.
