Subject: [PATCH] Delete python bytecode before every test run

Because python creates pyc|pyo files and __pycache__
directories during tox runs, certain changes in the tree,
like deletes of files, or switching branches, can create
spurious errors.

Change-Id: Ibaac514521bab11bbf552e0310d1203230c0d984
