Added support for autoTrackVirtualPages when using ui-router

https://github.com/angular-ui/ui-router does not emit the event
$routeChangeSuccess but the event $stateChangeSuccess.

When using ui-router you will probably want to use
$analyticsProvider.firstPageview(false);. Otherwise you will track the
first page view twice.
Fixed spelling in test
Revert 12b5054..8548794

This rolls back to commit 12b5054d19a32360f8fdde39cde1a79a2cc40264.
Changed binding to the event '$locationChangeSuccess'

The event '$locationChangeSuccess' is emitted from the $location
service.
If we listen to this event, angulartics will become router module
agnostic! :)
Changed test to '... location change'
