Tadeu Zagallo c2fb21b322 [ReactNative] Properly pause frame update observers when idle
Summary:
@public

`RCTDispatchEvent` and `RCTTiming` weren't being paused when there wasn't any
work left to be done.

Test Plan:
Run the timers example - check everything still works as expected
Test the ListView paging example - check scroll events are still fired as expected
Launch UIExplorer, let it idle, and put a break point on `-[RCTBridge dispatchBlock:moduleID:]`,
it should never fire.
