tests: switch to 4 space indent

Reformat this dir by itself to help merging with conflicts with other CLs.

Reformatted using:
parallel ./yapf -i -- tests/*.py
~/chromiumos/chromite/contrib/reflow_overlong_comments tests/*.py

These files still had lines (strings) that were too long, so the pylint
warnings were suppressed with a TODO.
