bug: $ionicSlideBoxDelegate.next() causing an exception after upgrading to 1.0.0

Type: <span ionic-type>bug</span>

Platform: <span ionic-platform>mobile</span> <span ionic-webview>webview</span>

<span ionic-description>I just upgraded to 1.0.0 yay me but this is the only thing I can’t figure out.

When calling any function that moves to the next slide such as this one

$ionicSlideBoxDelegate.next()

This is the exception that I get…

TypeError: Cannot read property 'length' of undefined
    at circle (http://localhost:8100/vendor/ionic/js/ionic.bundle.js:8050:21)
    at slide (http://localhost:8100/vendor/ionic/js/ionic.bundle.js:8079:14)
    at ionic.views.Slider.ionic.views.View.inherit.initialize.slide.select (http://localhost:8100/vendor/ionic/js/ionic.bundle.js:8432:7)
    at http://localhost:8100/vendor/ionic/js/ionic.bundle.js:105:46
    at Array.forEach (native)

when diving into the code, the slides variable gets undefined.</span>

I get the same issue using $ionicSlideBoxDelegate.next();. It seems that adding delegate-handle="slider" to the <ion-slide-box> in the template and referencing it using $ionicSlideBoxDelegate.$getByHandle('slider').next(); and $ionicSlideBoxDelegate.$getByHandle('slider').previous(); work reliably in 1.1.0 though

Having same issue here too, neither of the solutions above worked for me.
