test: update how cmi is tested so it doesn't use the `.tar.gz` files

[cadenmyers13]

Problem

Tests are ran on CI with cmi install _tests profile which loads packages and runs tests from packages located here requirements/packs/scripts/tar_url.txt. This has caused issues in the past and requires us to update these file links as we update and change code.

Proposed solution

First, we need to understand exactly what this test is doing. Then, lets see if we can find a test that covers the same behavior without the extra maintenance.

@cadenmyers13 is this closed by the latest release?
