Bug 1223739 - Travis: Put etl tests in the 2nd chunk to balance runtimes

Previously the python chunks were approx 3m55s and 2m55s respectively,
since we couldn't move one of the largest running directories (etl) to
the second chunk, since the tests would fail due to bug 1219922.

After this change the python chunk runtimes are 3m15s and 3m25s.
