Fixes broken ansible-config tests

The tests weren't flake8 compliant, which CI did not caught. There were
two separate tests identically named, so one got clobbered and
effectively we weren't testing both required attributes.

The test file now *does* pass flake8, which I confirmed via manual
invocation against it. Opened a separate issue, #2933, to track
improving CI to avoid this problem in the future.
