An example test, exposing #378
Fixes #378 by using the GraphDatabaseApI interface and trying to log exceptions in that behaviour
Reworked log messages to make them cleaner
There was a test in Neo4jGraphTest that didn't correctly shutdown the graph.
To find the right one, I added a kind of fail early in deleteDirectory, ensuring this method fail when directory can't be deleted. This way, each Neo4j test that do not properly close the graph will show up immediatly.
commented out the thrown exception as it make the whole OrientDB fail.
Removed unused import.
Some comments around BaseTest for Blueprints test suite.
