Subject: [PATCH] make sure onLayout calls _updateViewableItems immediately

Summary:
Makes sure `onViewableItemsChanged` fires ASAP when `waitForInterations` is false.

This also works around another deeper bug where updates scheduled with `InteractionManager` aren't firing at all in some cases, and thus instead of just firing late, `onViewableItemsChanged` isn't firing until scroll which is not what we want with `waitForInterations: false`. That bug will require more digging.
