Title: Fix for `Tag#dom_class_name_for`

In the less common case when a resource doesn't respond to `#model_name`
`Tag#dom_class_name_for` previously called `#underscore` on the class.

I've changed this to call `#underscore` on the class name as
`#underscore` is a standard (`ActiveSupport`) method on `String` but not
on `Class`.
