Exclude extra.server fields from exceptions_json.log

See merge request gitlab-org/gitlab!32770

These fields aren't really useful in a log, because we should know what

volume.

Using cop to find offences

- models folder
- specs folder

- Update specs to match

Previously `ArtifactsController#latest_succeeded` might return 404s even
though `ArtifactsController#download` would successfully return an
artifact. For example, this could happen when:

1. A new commit was merged to `master`.
2. A user attempts to download the artifact for `master` before the
pipeline for `master` finishes, or the pipeline fails altogether.

To fix this problem, we fallback to looking up a successful pipelines by
ref name if one doesn't exist for the SHA.

This fixes an issue in Elasticsearch 7.7+ versions
(https://gitlab.com/gitlab-org/gitlab/-/issues/218324). Previously the
query parser was forgiving about nested arrays and would just
automatically flatten them for you but now we need to flatten them
ourselves.
