Job details sidebar breaks when using `artifacts:access` or `artifacts:public` keyword

Summary

When using one of the following CI config settings for a job:

• artifacts:access set to developer or none
• artifacts:public set to false

the Job details page fails to load the sidebar when viewing as someone who can't see the artifact.

Steps to reproduce

• Create a job in a public project that uploads an artifact
• Set the keyword artifacts:access to developer
• Run the pipeline
• View the job from a role that is not a developer+ of the project (just open incognito and go to the job details page)
• See that the sidebar does not load

What is the current bug behavior?

The sidebar doesn't load

What is the expected correct behavior?

The sidebar should load, but the buttons to view the artifacts should not appear.

Possible fixes

Looks like it's something to do with the hasArtifact() function in the sidebar.vue file.
