Metanome-cli Tane algorithm crashed

[MurikiGY]

After my problem in #437 was solved, I got another error:

(metanome-cli) INFO     Running de.metanome.algorithms.tane.TaneAlgorithm

The command:

java -cp metanome-cli-1.2-SNAPSHOT.jar:TANE-1.2-SNAPSHOT.jar de.metanome.cli.App --algorithm de.metanome.algorithms.tane.TaneAlgorithm --file-key INPUT_GENERATOR --files WDC_satellites.csv --header
