Merge branch 'adam-fix-labels-find-or-create' into 'master'

Pass user instance to Labels::FindOrCreateService or skip_authorization: true

## What does this MR do?

It fixes a bug described in #23694 when `project.owner` was passed to `Labels::FindOrCreateService`. `Labels::FindOrCreateService` expected a user instance and `project.owner` may return a group as well. This MR makes sure that we either pass a user instance or `skip_authorization: true`.

## Are there points in the code the reviewer needs to double check?

- places where we pass `skip_authorization: true`
