Title: Fixed trouble when i tryied to validate something in context of BusyButton onClick

I found this bug in next case :

```javascript
require(["dojox/form/BusyButton", "dojo/on"], function (Button, on){
var t = new Button({label: 'Avail',
busyLabel: 'Busy'});
t.placeAt(dojo.body());
on(t, 'click', function (){
// Invalid validation
t.cancel();
});
})
```
