Fix build attributes test, see:

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/9021#note_23782188

This is discovered by
https://gitlab.com/gitlab-org/gitlab-ce/builds/10815456

I removed `gl_project_id` and this is failing. I took some look,
realizing that:

* `trace` is duplicated in `attributes`
* `tag_list` is not included in `build.attributes`
* `artifacts_expire_at` is missing in `attributes`

So we need to:

* Remove duplicated `trace` in `attributes` (40 -> 39)
* Remove `tag_list` in `attributes` (39 -> 38)
* Add `artifacts_expire_at` to `attributes` (38 -> 39)
* Add `gl_project_id` to `attributes` (39 -> 40)
