Title: changed #determine_redis_provider to first check REDIS_PROVIDER

This bit us when we had two Redis providers on Heroku for a brief time to migrate to a different provider other than RedisToGo. I think the REDIS_PROVIDER or REDIS_URL environment variables should take precedence over the specific REDISTOGO_URL for the RedisToGo provider.
