Should redirect to login if try to create team if no teams and when not yet authorized yet

when you first run it in a development environment, the page http://localhost:3000/teams loads.
if you haven't bothered to run rake db:seed, then it gives you the option to click "There are no teams yet. Maybe create your own?" it takes you to http://localhost:3000/teams/new, but i think it should fail gracefully and notify the user that they need to login first if they haven't already and redirect them to login.
at the moment if they haven't logged in it shows error Pundit::NotAuthorizedError at /teams/new crashing on line 11 in app/controllers/hacking_teams_controller.rb
