inView stays true when component is unmounted

[chapa]

Hello,

When the component holding the ref is unmounted while it was visible, the inView stays true.

Here's a fork of your basic example using useInView : https://codesandbox.io/s/react-intersection-observer-2rdzd
Click on the button to unmount the <Wrapper> component which holds the ref, the status at the top-right corner stays green

That's a use case I haven't considered. Makes sense that it clears the state.
Should be a matter of resetting the state if the ref changes.
