Inconsistent specification of stage: test in Auto DevOps

There's an inconsistent use of stage: test in Auto DevOps jobs. The test job states this, but others like codequality and performance infer it (test is the default stage if stage is not specified).

I believe it would be clearer if all the test stage jobs stated stage: test for consistency and clarity.

Has test stage:

test:
  services:
    - postgres:latest
  variables:
    POSTGRES_DB: test
  stage: test
  image: gliderlabs/herokuish:latest
  script:
    - setup_test_db
    - cp -R . /tmp/app
    - /bin/herokuish buildpack test
  only:
    - branches

Implied test stage:

codequality:
  image: docker:latest
  variables:
    DOCKER_DRIVER: overlay2
  allow_failure: true
  services:
    - docker:dind
  script:
    - setup_docker
    - codeclimate
  artifacts:
    paths: [codeclimate.json]
