More complete fix for 39692

The existing fix did not work if the profile name itself had a dash `-`.
For example - `virtual-guest`. This commit fixes that by using `split('- ')`
rather than `split('-')`. This commit also provides two simple tests for the
`list_()` function to emulate behaviour of both old and new tuned-adm versions

Fixes #39692
