When a project is disabled, visiting the home page would show,
"An error occurred while loading commit signatures". This change checks
that the user has permission to view the project to avoid unnecessary
GPG signature lookups.

Add stage name in job.json response

Closes #52618

See merge request gitlab-org/gitlab-ce!22317

The function that was checking if the job was started or not
was expecting a boolean, however it was receiving a null.

to break with null
