session/test_env_select: Reformat from tox -e fix

I find this makes the tests significantly less readable, so I'm commiting
this separately so we can decide what to do about it. The options are:

1. Squash this with the previous, just using the auto-enforced formatting.
2. Leave these commits as-is, so we at least can go back to the more
   readable original formatting.
3. Do whatever needs to be done to keep the auto-reformatter from touching
   that particular bit of code.

I have a preference for 3, but won't argue any other decision.
