Summary:
The component RCTRefreshControl was renamed to PullToRefreshView (for Paper). Now only old Objective-C class names have the old name, which is okay.
Changelog: [Internal] [Changed] - The internal name of PullToRefresh component was changed from `RCTRefreshControl` to `PullToRefreshView` (No public API changes)
