This unittest was broken from running locally because it imports pretty printer modules from the project root src directory. This works in evergreen where PYTHONPATH is setup to add the src dir: https://github.com/mongodb/mongo/blob/af6adde067d69512c2a9167e83baf0fc7cf02501/evergreen/prelude_venv.sh#L26

We will align with that for now and locally add the src dir to the path. This will break self testable installs (even further then it already is)
