Anycable problem solved

Leaving this, might help others:

I tried this with any cable and I had to add this to `development.rb`
Otherwise @instance_variables were `nil` after a reflex

```ruby
  config.cache_store = :redis_cache_store, { url: "redis://localhost:6379/1", driver: :hiredis }
  config.session_store :cache_store
```
