The CI builds the Nautobot container 2 times in the `unittests` step

[ubajze]

Environment

• Python version: any
• Nautobot version: any
• nautobot-golden-config version: any

When running the unittests step the container is built two times. The possible reason is the mismatch in tags. Here is an example: https://github.com/nautobot/nautobot-plugin-golden-config/runs/7813649743?check_suite_focus=true

Steps to Reproduce

1. Run the unittests step in the CI

Expected Behavior

Just run the build process and then tests without re-building containers.

Observed Behavior

The build process is executed 2 times, which extends the CI pipeline execution.
