No services listed in 2.x docs

# Bug Report

#### Current Behavior:

https://ui-router.github.io/ng2/docs/latest/ doesn't list any services nor other classes in the right sidebar. Nor does the search work for the available services. Last version for which this works is 7.0.0.

#### Expected Behavior:

It should list all available service for angular-ui-router 2.x, like e.g. StateService and the search bar should be usage to find them as well.
