Fix or remove @Ignore in DsTestCase

We are in the process of a major test infrastructure update. For this I migrated all smoke tests the the managed container. The arquillian subsystem has been replaced by a on-demand deployment. Your test might be @Ignored because I could not fix it easily or it has already been ignored for some time. Please have a look if you can fix it, otherwise I'd like to know why it should be ignored.
