🐛 : Remove events on unmount, delete dead code

[natseg]

Hi,

I was experiencing an issue with a click triggering an event even after a component had unmounted. Maybe I misunderstood the intentions behind event management.

Let me know if it's ok.

Thanks

Cool thanks!, do you think you can add a unit test here? https://github.com/aframevr/aframe-react/blob/master/tests/browser/index.test.js ... use the events prop, then detach the component, and emit an event to make sure a callback is not called

Yes, done deal.

Thank you for creating this!
