- Fix custom unit tests that was not ran by surefire maven goal (testShutdownStartManyTimes, testMVertexHashCodeAndEquals and testMEdgeHashCodeAndEquals)
- Remove 4 useless suites testing graph import feature (testGraphFileTypeJava, testGraphFileTypeGML, testGraphFileTypeGraphML and testGraphFileTypeGraphSON): those suites were actually testing the TinkerGraph implementation, and related features are (not yet) implemented by MapDBGraph
- Clean code typo and format on related tests files
