Title: More fixes for resolve keypath expressions

Hey @Rich-Harris looking good, except for one issue #605. Here's the test:
```js
var ractive = new Ractive({
el: fixture,
template: "{{#step}}{{#options}}{{/}}{{/}}",
data: {
step: {
name: 'Products',
options: ['1', '2']
},
responses: {}
}
})
ractive.set('step', {
name: 'Colors',
options: ['red', 'blue', 'yellow']
})

expect(3)
ractive.findAll('input').forEach(function(input){
t.equal( input.name, '{{responses.Colors}}' )
})
```

The `KeypathExpressionResolver` is returning the correct new values, but the `input name` attribute is never rebinding to the new values. I'll key looking, but if you have any ideas let me know...
