Can not run tests on deeply nested charts

[SleepWalker]

In case when you have subcharts of subcharts, e.g. root/charts/foo/charts/bar/templates/deployment.yaml it's not possible run tests on them.

I've tried to run tests in two ways:

• from the root chart's tests (root/tests) by adding corresponding paths in templates:
• by creating tests in subchart (root/charts/foo/tests) and running unittest from the project root

In both cases I'm getting the following error:

        - manifest should match snapshot

                - asserts[0] `matchSnapshot` fail
                        Error:
                                template "root/charts/foo/charts/bar/templates/deployment.yaml" not exists or not selected in test suite

The only way it currently works if I navigate to root/charts/foo and run unittest from there.
