InterceptorUnit test does not register actionName

[sbglasius]

With an interceptor like this:

class ActionNameInterceptor {
    boolean before() {
        println "$controllerName $actionName $params"
        if (actionName) {
            request.setAttribute('actionNameSet', 'action name set')
        }
        return true
    }
}

When running, the actionName is set, but when running tests, the actionName is not set.
