Issue:
ontapi: do not allow OntDisjoints with no items
### Version

5.2.0

### What happened?

this is bug, regression of 73699fc1b1268f97121d6e292dafdbd1849cd879 (the problem was found while running owlcs/ont-api tests)

When there is no items it is impossible to distinguish `OntDisjoint.ObjectProperties` and `OntDisjoint.DataProperties`, which currently leads to wrong situation when `OntDisjoint.DataProperties` treated as `OntDisjoint.ObjectProperties` (because the last one has more priority).
Moreover, such `OntDisjoint`s do not make sense, so there must be at least one element even for DL/FULL.

The test-case for catching problem:
```java
        var m = ModelFactory.createDefaultModel().setNsPrefixes(PrefixMapping.Standard);
        var p1 = m.createResource("p1", OWL.DatatypeProperty);
        var p2 = m.createResource("p2", OWL.DatatypeProperty);
        var d = m.createResource().addProperty(RDF.type, OWL.AllDisjointProperties);
        var list = m.createList(p1, p2);
        d.addProperty(OWL.members, list);

        var ont = OntModelFactory.createModel(m.getGraph());
        var actual1 = ont.ontObjects(OntDisjoint.DataProperties.class).toList();
        Assertions.assertEquals(1, actual1.size());

        var actual2 = ont.ontObjects(OntDisjoint.ObjectProperties.class).toList();
        Assertions.assertEquals(0, actual2.size());

        var actual3 = ont.ontObjects(OntDisjoint.class).toList();
        Assertions.assertEquals(1, actual3.size());
        Assertions.assertEquals(OntDisjoint.DataProperties.class, OntModels.getOntType(actual3.get(0)));
```
