Executing `bob.bio.vein` experiments with `biowave_test` database only group `dev` `enroll` data are run

Executing bob.bio.vein experiments with biowave_test database only group dev enroll data are run. The bob.bio.vein experiments are run with the following command:

$  ./bin/verify.py --database biowave_test --preprocessor topography-cut-roi --extractor maximumcurvature --algorithm match-mc --protocol all --sub-directory /idiap/home/teglitis/Desktop/Experiment_biowave_test/ --grid demanding -vv

Using the biowave_test databases only protocol -- all. I just changed the biowave_test low level interface so that model_ids also accepts group and protocol (this is merged in master branch in bob.db.biowave_test by me). High level implementation can be found in bob.bio.db branch biowave_test_isiues (https://gitlab.idiap.ch/bob/bob.bio.db/commits/biowave_test_isiues)

When results are computed, only scores_dev file can be found that consists of only genuine scores.
