As mentioned here, the original intent was for this declaration to override the unicorn restart command declared [in the base opsworks recipes](https://github.com/aws/opsworks-cookbooks/blob/master-chef-11.4/rails/recipes/configure.rb#L6). I'm not 100% sure if that is still necessary, but would rather be safe.

On the other hand, I'm happy to merge if you can test and confirm that the renamed command works through the various lifecycle events.
