Fix the test_KMeans_libsvm_fvec test. Pass all columns to KMeans to avoid passing a 6k-long array of column indices to ignore, which broke the connection. Also remove one libSVM datasets from this KMeans test, took too long for Summary2.
Fix the test_KMeans_libsvm_fvec test.
Pass all columns to KMeans to avoid passing a 6k-long array of column indices
to ignore, which broke the connection.
Also remove one libSVM datasets from this KMeans test, took too long for Summary2.

Note: This test is mostly an Import/Inspect/Summary2 test.
