tauto - re-add inits and tests/* for now to support proper packaging (8)

tests/* are required by some deeper parts of the job.py setups. And
simply removing those lines of code requires more un-tangling. For now,
just add the tests/* back in.

Additionally, __init__ is needed in the test dirs so that they are
properly packaged into tauto client
