STANBOL-1127: fixed several issues with the integration-tests: fixed rdf files with syntax errors in the apache-project-doap-files.zip; fixed some regex expressions used in assertions for expected content; fixed some requests to use the application/x-www-form-urlencoded Content-Type; NOTE: there are still three failing integration tests for the entityhub because of an error related to serializing JSON-LD
