Disable harmful rake tasks in production

No need to check whether you are running that `bundle exec rake db:reset`
command on staging or production anymore 😱.

As described in https://github.com/adamcooke/rails-safe-tasks

> This gem provides an extra layer of safety between you and deleting all your
> production data by accident.

> It restricts the use of various rake tasks (including db:drop, db:reset etc...)
> when you are running your application in a production environment.
