bug fix

fixed bug that caused
xgboost.core.XGBoostError: [16:53:22] ../src/data/data.cc:530: Check failed: labels_.Size() == num_row_ (324 vs. 223) : Size of labels must equal to number of rows.
when running the hello world example twice,
caused by a missing new feature extraction when new test speakers were selected but the old features sets were reused.
Can happen when split_strategy = speaker_split

['FEATS']['needs_feature_extraction'] = 'True'
