Reproduction of the problem

1. Set the Create end point to throw an error, e.g: throw new Exception("some message");
2. Click the New Folder button in the FileManager

Current behavior

The FileManager's Error event fires, its dataSource throws a js exception:
kendo.all.js:165968 Uncaught Error: Error! The requested URL returned 500 - error

and the added folder is still displayed in the FileManager view.

Expected/desired behavior

The view is refreshed and the added folder is removed.
