Fix assertions in test result validation

The test assertion mechanism was updated in the project service validation tests. Instead of checking presence of every expected key into the result keys set individually, now the equality of sets is checked. Additionally, data for a non-existent module was added to the pkgs-test-java.json, this will help testing scenarios where the tested project doesn't have some prerequisites.
