Redis tries to connect to localhost on Heroku instead of REDIS_URL

I have a Rails app which uses Redis for background jobs. On Heroku I use the Heroku Redis add-on. When I deploy to Heroku, it gives me this error:

Redis::CannotConnectError: Error connecting to Redis on 127.0.0.1:6379

It seems it tries to connect to localhost. I have both a REDIS_URL and REDIS_PROVIDER environment variable on Heroku. And this is how my redis.rb looks like:

if Rails.env.production?  uri = URI.parse(ENV["REDIS_URL"])else  uri = URI.parse("redis://localhost:6379")endResque.redis = Redis.new(:host => uri.host, :port => uri.port, :password => uri.password)

And this is my Procfile:

web: bundle exec unicorn -p $PORT -c ./config/unicorn.rbworker: env TERM_CHILD=1 bundle exec rake environment resque:work QUEUE=* COUNT=1

Any ideas why it is not working? Even if I change redis.rb so it only has the REDIS_URL as url, it gives the same error.

Update: added error trace:
