CI test broken

Summary

Backup tests are broken in the latest master image. Impacting our master pipelines an any new feature branches.

The spec tests are failing during the backup specs, but the real error is sometimes being eaten in the logs. You can see the error, (a cipher error) in this job: https://gitlab.com/charts/gitlab/-/jobs/281635010

The error can be reproed from the task-runner pods just by trying to run db:migrate. There is likely a migration that has been added upstream that requires the runner secrets to be properly in place, and in our tests we don't restore that secret until after the migrations.

We need to move the runner token restore step in the tests to happen before the migration.
