Creating set of default labels uses false template

Summary

When a GitLab project has no labels anymore, it's possible to recreate all default labels by clicking "Create a default set of labels".
Unfortunately, the used template set of labels isn't the list of labels defined in /admin/labels.

Steps to reproduce

Create a repository and delete all project labels. Click on "Create a default set of labels". The created labels are not the same as created by GitLab when a new repository is created.

Example Project

Does not apply.

What is the current bug behavior?

The set of created labels is different from the list of labels specified in /admin/labels.

What is the expected correct behavior?

Create the set of labels based on the list specified in /admin/labels.
