migrate tests for PoddSesameManager.getTopObjects()
move 3-topobjects.ttl to api/src/test/resources
standardise on the inferred ontologies importing the concrete ontologies

this makes it possible to have a systematic alternative to the podd base
inferred version predicate that only works in the ontology manager
change contract on InferredOWLOntologyID so that the inferred ontology
does not come back with a version IRI
start the long boring process of migrating tests and code over to not
assume that inferred ontologies have version IRIs
add owl:imports triple back from inferred to concrete ontology

adds a new triple and deduplicates many statements
fix first test after change to the reasoner methodology
switch to compile dependency on owlapi-impl to get access to internal
class to make it easy to add an import
fix test numbers to reflect deduplicated statements
remove debug call
fix test numbers to reflect deduplicated statements
move out commented out tests
