Jeff Case beeffb89fe Made getItem and getItemCount required props (VirtualizedList) ...

Summary:
The main reason to use **VirtualizedList** is to set the `getItem` and `getItemCount` props, so having default values for these props makes things error prone.

* In **VirtualizedList**, changed the `getItem` and `getItemCount` props from optional to required, and removed default values.
* Ensured that implementing classes **FlatList** and **SectionVirtualizedList** are always passing these props.
* Updated VirtualizedList-test.js accordingly.
