Hotfix: removes set -u in tests/wait.sh to unblock CI on other open fortify MRs | SKIP UPGRADE

General MR

Summary

My addition of set -u (aka nounset mode^?) to tests/wait.sh for #52 (closed) has inadvertently broken some downstream CI jobs (see !121 (merged)). This hotfix removes set -u so that those jobs can proceed.

Relevant logs/screenshots

With set -u in force: jobs fail when they get to the second package_install in the upgrade CI job.

Relevant discussion threads:

• development & ops team chat on this error in !121 CI jobs
• guidance in pipelines & infra room on not trying to fix this at the pipeline-templates level just yet due to potential for further unanticipated downstream errors
