Title: Bug fix in nilearn/group_sparse_covariance.py

in function 'group_sparse_covariance_path':
test covariances are now only computed if 'test_subjs is not None', i.e., if test_subjects are given. Previously this returned a ValueError since the covariance of a NoneType object cannot be computed.
