[0.10.3] RaisedButton requires double click

Since the 0.10.3 release `RaisedButton` now only fires `onClick` when you click on it a second time. Reverting to 0.10.2 fixes this.

The code is:

``` jsx
<RaisedButton label="Submit" primary={true} onClick={this.submit} />
```

`this.submit` is only called on the second click.
