[NavigatorIOS] Calling navigator.replace doesn't change the title

[arypurnomoz]

After calling navigator.replace, the view is changed, but the navigator titles stay the same

var style = StyleSheet.create({
  text: {
    marginTop: 80,
    fontSize:32
  },
})

var Hello = React.createClass({
  render():?ReactElement {
    return <Text style={style.text}>Hello</Text>
  },
  componentDidMount() {
    setTimeout(()=> {
      this.props.navigator.replace({title:"Updated", component: World, leftButtonTitle:"LEFT"})
    }, 3000)
  }
})

var World = React.createClass({
  render():?ReactElement {
    return <Text style={style.text}>World</Text>
  },
})

var Nav = React.createClass({
  render():?ReactElement {
    return (
      <NavigatorIOS style={{flex:1}} initialRoute={{title:"Init", component: Hello, leftButtonTitle:"Left"}}/>
    )
  },
})

Can you give a bit more context? or perhaps a code sample

I think this is the same issue as #476
