Swagger - Update Api

[xstable]

I got this message in the Backend if I wan't to open the API-Docs:

You are looking at an outdated version of the api documentation. Please run the rake task `redmine:plugins:hourglass:api_docs` to update or ask an admin to run it for you.

If I go to /plugins at server, and execute: bundle exec rake redmine:plugins:hourglass:api_docs, I got:

 bundle exec rake redmine:plugins:hourglass:api_docs
