Selecting Auto DevOps Deploy Strategy to manual makes build job spin

Summary

When setting up Auto DevOps for a project, if you select the second option under Deploy Strategy (Automatic deployment to staging, manual deployment to production) then build jobs spin endlessly.

Steps to reproduce

  1. Make a new project
  2. Set the project's CI/CD Auto DevOps settings
  3. For Deploy Strategy select "Automatic deployment to staging, manual deployment to production" option
  4. run a pipeline to build a simple project
  5. build stage will spin forever, with no output
  6. Changing the setting back to "Continuous deployment to production" makes the problem go away.
