Fix bootstrap pipeline tests (#679)

**Why?**

The tests that execute in the aws-deployment-framework-bootstrap pipeline
failed.

They failed, as the tests picked up environment variables from the actual ADF
installation. Rather than the test environment they run in normally.

**What?**

Fixed by running the tests using tox. Such that the test environment is
created. This ensure the tests are consistent regardless of where they execute.
