RadListView PullToRefresh leaves gap on iOS

[JWiseCoder]

In iOS, after a pull to refresh, there is sometimes a gap at the top of the RadListView, even after calling notifyPullToRefreshFinished. This seems to happen only when the number of items before and after the refresh is the same. If the number of items change, there is no gap afterwards.

This is similar to the #278, but this is still happening with the latest version.

Try running listViewElement.nativeElement.refresh() when the notifyPullToRefreshFinished event is triggered.

Same issue here, and can't fix it with a refresh on my listView. Any clues ?
