Fixing the updating phase in the react component lifecycle

[glrodasz]

There is an issue on section 6.7 where the update lifecycle is wrong, it says:

Updating Phase follows this order:
componentWillReceiveProps()
shouldComponentUpdate()
render()
Children Life cycle methods
componentWillUpdate()

But it should be:

Updating Phase follows this order:
componentWillReceiveProps()
shouldComponentUpdate()
componentWillUpdate()
render()
Children Life cycle methods
componentDidUpdate()
