Refactor Listview to solve a bug

Summary:
There was a bug in ListView where the selected items where not getting updated.

Bug

In the following video I have selected Inspector and logs plugin from export drop down. When I click on litho support form it should select the default plugins which is Inspector, Mobile Config and Logs. But it only shows Inspector and Logs selected

{F226900949}

To fix it:

I call the callback `onChange` when the listview's row get updated, which will updates the props of the ListView component and hence rerendering it with updated selected rows.
