TreeGrid Aggregate does not work in IE

[Marek Mihalech]

TreeGrid aggregate is not working in IE at all - it show error: "Object.keys: argument is not an Object" 

It even does not work on official documentation in IE here (Preview tab): https://ej2.syncfusion.com/javascript/documentation/treegrid/aggregates/#child-aggregate

My IE version is 11.0.9600.19155

I have also created issue on github: https://github.com/syncfusion/ej2-javascript-ui-controls/issues/53

The above reported issue is already known issue and we have fixed it. And the same will be included in our next release volume 2 2019, which is expected to be rolled out in the mid of July 2019. 

Till then, we appreciate your patience.
