QueryExpander.getDirectSubClasses wont get subclasses of restriction

[djogopatrao]

test:

java -jar target/SPARQLFederator-1.1-SNAPSHOT-jar-with-dependencies.jar -query "http://www.cipe.accamargo.org.br/ontologias/domain.owl#prop some http://www.cipe.accamargo.org.br/ontologias/domain.owl#G" -domain_ontology examples/live_example_property/domain.owl -federation_ontology examples/live_example_property/federation.owl -exec print -query_type dl

it should recognize class "D" as subclass of "prop some G", but it doesn't.
