Summary: Add a `console.warn()` call when calling `_scrollRef.scrollTo`, because `scrollTo` is not guaranteed to exist on `_scrollRef`. Context: `VirtualizedList` holds `_scrollRef`, which is usually a reference to a `ScrollView` component. However, there are several cases where it holds a `View` or other type of component instead. A custom component can be passed in to `renderScrollComponent`, and then `_scrollRef` will point to that custom component. Additionally, if two VirtualizedLists are nested with the same orientation, `_defaultRenderScrollComponent` will return a View instead of a ScrollView. Due to these possibilities, `_scrollRef` is not guaranteed to have a `scrollTo` method.
