Clicking on the FileExplorer's Refresh button does not refresh the pager of the control properly when the currently selected page in the grid/listview is bigger than 1.

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/fileexplorer/examples/server-sideapi/initialpathandpaging/defaultcs.aspx
2. Navigate to some page (e.g. 3) in the FileExplorer's grid/listview
3. Refresh the control (click the "Refresh" button on the toolbar)

Result: FileExplorer shows the content if the first page, while the pager keeps the state from before the refresh (e.g. 3).
