Avoid failing terraform test whenever there is no access to the secret

[enolfc]

Short Description of the issue

When a PR is opened to this repo from a fork, the terraform action will fail as it does not have access to the secret to obtain the token. We should avoid that but still somehow test that we can deploy.
