Incorrect URL

[senfo]

Given the following:

var API = Phonebook.open({
url: '/',
options: {
dataType: 'json'
},
data: {}
});

API.addChapter({
name: 'events',
url: '/events'
});

API.events.get();

Phonebook will attempt a GET request to http://localhost/eventsundefined

Based on my understanding of the documentation (and expectations), I shouldn't have to pass the URL in the get() method, but I'm able to get around the issue by doing the following:

API.events.get('');

The get() function already has the chapters url at this point, but it doesn't look like it's using it.
