Enable getDerivedStateFromError (facebook#13746)
* Removed the enableGetDerivedStateFromCatch feature flag (aka permanently enabled the feature) * Forked/copied ReactErrorBoundaries to ReactLegacyErrorBoundaries for testing componentDidCatch * Updated error boundaries tests to apply to getDerivedStateFromCatch * Renamed getDerivedStateFromCatch -> getDerivedStateFromError * Warn if boundary with only componentDidCatch swallows error * Fixed a subtle reconciliation bug with render phase error boundary
