… Fabric (facebook#27687) (facebook#41452) Summary: ## Summary This fixes an error in `getPublicInstanceFromInstanceHandle` where we throw an error when trying to access the public instance from the fiber of an unmounted component. This shouldn't throw but return `null` instead. ## How did you test this change? Updated unit tests.
