test_rf_VA_simple_example.py wasn't a test, renamed
the GBM tests were doing fvec parse and failed. changed to VA parse.

test_GLM_from_import.py had the old '0' col name

moved the PCA tests back into testdir_single_jvm

changed test_parse_header_rows_mismatch.py to import folder rather than put/upload ..still fails, but easier to see it's got the commands to h2o correct
