Nav menu breaks for custom routes

[ryanb]

I have a custom route to add a custom action like this:

resources :accounts do
  member do
    get :extend_trial
  end
end

This causes the Data menu to disappear when visiting the account pages because it loses reference to current_engine.

I tried specifying the engine_name in the controller:

self.engine_name = "wallaby_engine"

However this causes another error:

ActionController::UrlGenerationError - No route matches {:action=>"index", :controller=>"support_admin/accounts", :sort=>"id asc"}, missing required keys: [:resources]

Not certain how to proceed from here.
