Skip tests that have never been run with CI since they were added

The spec file was named incorrectly in 23db5ed as:
spec/models/manageiq/providers/autosde/storage_manager/refresher_spec_v2.rb

Spec files should match the glob pattern "*_spec.rb".  We need to come back
and make these tests work since the file has been renamed correctly.
