Simplify obtaining the playbackDependency

[dennis-behm]

This is simplifying the ZUnitConfig.groovy and fixes #390

@drbruce-git I agree, that a new test case for this section of the code makes sense. However, the code change is very small. I think it requires to add a new test application, which includes a IDZ zunit test configuration. Let's treat this as a separate issue. Would you be okay with this approach?

[drbruce-git]

@dennis-behm OK we can table the new test case for zunit testing for later. However can we still get the results of the existing regression tests? Also we need to figure out how to add a successful regression test run to the PR checks.
