Updated and re-activated test for LoadEmbeddedOntologies
Don't try and fetch ontology from ontologyIRI if it is the same as the source IRI that already failed
Should also use the apikey when accessing an ontology via the old bioportal API url
Bumped network timeout from 30 to 120 seconds
Just log an OWLOntologyAlreadyExistsException when loading embedded ontologies

rather than popping up an error box
Updated bioportal ontology format cache, and put logging back to warn
