Subject: [PATCH] added if statement in onRemove() function

Added an if statement in onRemove() function that checks if "this.div" is defined before calling ReactDOM.unmountComponentAtNode(this.div). This is done to avoid throwing an "unmountComponentAtNode(...): Target container is not a DOM element" error. I ran into this error while using google-map-react with React Router and switching between tabs rapidly to stress test my application.
