Handling new props

[rdiazv]

_initFromProps () {
  const targetItems = this._initSpyTarget(this.props.items)
  ...
}

componentWillReceiveProps () {
  this._initFromProps()
}

this.props.items are still the old items when calling _initFromProps in componentWillReceiveProps, so the component don't actually update.

I had to include jsdom to handle document.getElementById in the tests.

I'm having trouble with jsdom on Travis CI... any thoughts?

@rdiazv From the log of travis ci, it seems to be an issue with installing contextify that is a dependency of jsdom.
