frontend-collective-react-dnd-scrollzone has dependency issues

Looking at the requires for that frontend-collective-react-dnd-scrollzone in package.json, it's messed up:
```
"frontend-collective-react-dnd-scrollzone": {
"version": "1.0.2",
...
"requires": {
"hoist-non-react-statics": "^3.1.0",
"lodash.throttle": "^4.0.1",
"prop-types": "^15.5.9",
"raf": "^3.2.0",
"react": "^16.3.0",
"react-display-name": "^0.2.0",
"react-dom": "^16.3.0"
}
},
```

This is a dependency of react-storable-tree@2.7.1. This should not require react, react-dom in the released package. This is making react/react-dom load twice in my app and I can't use the control. Jest tests are failing etc due to multiple react versions being loaded etc.
