[TIMOB-3038] iOS clearOnEdit on textFiled clears value but retains info

Simple test:

var win = Titanium.UI.createWindow({
    backgroundColor:'#fff'
});

var field = Titanium.UI.createTextField({
    color:'#000',
    font:{fontSize:16,fontWeight:'bold', fontFamily:'Arial'},
    backgroundColor:'#fff',
    borderColor:'#000',
    value:'',
    height:50,
    top:10,
    clearOnEdit:true
});
var button = Ti.UI.createButton({top:100,width:200,height:50,title:'here'});
win.add(field);
win.add(button);

field.addEventListener('focus',function(e){
    alert('textfield value: '+e.value);
});

button.addEventListener('click',function(e){
    field.blur();
    alert('textfield value: '+field.value);
});


win.open();

To reproduce:
1. click on the text field and type something
2. click on the button to see the text field value
3. click on the text field again and the value is gone as expected (do not type anything)
4. click on the button again and you'll see the old text field's value

The alert on focus will show the value of the text field, which is gone on focus as expected, but mysteriously reappears afterwards.
