Calling onResize callback after the component is unmounted

[cecigarcia]

Despite the elementResizeDetector listener is uninstalled before the ContainerDimensions component gets unmounted, I got this warning:

"Warning: Can only update a mounted or mounting component. This usually means you called setState, replaceState, or forceUpdate on an unmounted component. This is a no-op.
Please check the code for the ContainerDimensions component."

I only get this warning in a particular scenario where the ContainerDimensions component is rendered in a tab menu component, but I can't figure out why this case is so particular.

I temporarily fix it by adding an instance variable set to true before the onResize callback is called in componentDidMount lifecycle method, set to false in componentWillUnmount and checked before calling setState in the onResize callback.

I suppose it's not a problem with this library itself but with the element-resize-detector library. I hope you could sort it out anyway.
