[PR3] Numberfields with a value attribute config always return their initial value

[stefankendall]

When I give a numberfield a value initializer, calling Ext.getCmp('myid').getValue() always returns the configured initializer.

I have this:

{
            xtype:'formpanel',
            items:[
                {
                    xtype:'fieldset',
                      defaults:{
                        labelWidth:'35%',
                    },
                    items:[
                        {
                            id:'myId',
                            xtype:'numberfield',
                            name:'something',
                            label:'something'
                            value:200
                        }]
                }]
}

getValue() is always returning 200. If I remove the value:200 config, I start getting the actual value of the input this component is controlling
