Everything looks good to me at first glance, I'll run the test locally and circle back

Please update the test-requirements.txt and check if tests are now passing too

Hi @hoangtrann, thanks for the review.

• Removed the migration-related inline comments you pointed out.
• Dropped the temporary test-requirements.txt (git URL refs) and restored requirements.txt.
• Rebased on latest 19.0, then squashed everything into a single [19.0][MIG] queue_job_batch: migrate commit.

CI is green now. @sbidoul
