Title: Ensure specified environment is used

If for any reason RAILS_ENV was set to test this command will start a
Rails server with test environment:

rails s -e development

But this one will start with development environment:

RAILS_ENV=development rails s

I am not sure who is at fault here, but this ensures guard-rails will
always use the environment specified by the environment option.
