Deduplicated many warnings (facebook#11140)

 * Deduplicated the following warnings:

1.  Can only update a mounted or mounting component.
    This usually means you called setState, replaceState,
    or forceUpdate on an unmounted component. This is a no-op

2.  %s.componentWillReceiveProps(): Assigning directly to
    this.state is deprecated (except inside a component's
    constructor). Use setState instead.'

3.  An update (setState, replaceState, or forceUpdate) was scheduled
    from inside an update function. Update functions should be pure,
    with zero side-effects. Consider using componentDidUpdate or a
    callback.

4.  setState(...): Cannot call setState() inside getChildContext()
