On `_handleDoneLeaving`, prevent calling `setState` if the component is unmounted. This was triggering this error: > Warning: setState(...): Can only update a mounted or mounting component. This usually means you called setState() on an unmounted component. This is a no-op. Please check the code for the ReactTransitionGroup component.

this component isn't the TransitionGroup instance. The error would be related to TransitionGroup not being mounted when setState is called, it'd be better to check if the current component is mounted

This happened on a very complex structure and I was not able to reproduce it with sample code.
It is related to #15.
