Demo in Heroku: «No such app»

[ivanhercaz]

If I access to the demo of the API in Heroku I get the notice: «No such app». Should the link to try it be removed or the demo site in Heroku should be fixed?

Checking clossed issues I found #9, which is practically the same issue. It reported the same, but I doesn't understand the reason of the link if it isn't available.

Does the readme need to be updated removing this link to avoid confusing? It is possible that I am not understanding its purpose.
