Only a ReactOwner can have refs

[shashikah]

Hi,
One of our application we are using react-notification-system. When it was a stand alone application all went well. Recently we had to change it as a npm package. We did it. When we use the npm package within a container app... it started to give us an error which says "Only a ReactOwner can have refs". When we dig into the bundle.js to find out the issue, we found that this comes from react-notification-system package. Is there a way we can get rid of using refs inside the package?

#144 should address this
