Commentator2.0 dbff52bfbc tests/functional2: improve commands ux
with_env now overrides the environment, similar to with_stdin
an additional function update_env was created to mirror the prior
functionality of with_env, updating the env

This was changed as previously it was impossible to delete variables
from the env

replaced the code of .ok() with a call to .expect, to remove the code
duplication
