[Bug]: [Low Priority] Cannot run tests from a test's local folder. conftest is not found.

[afourney]

Describe the bug

Prior to #1110, it was possible to run the tests from a test's local directory. E.g.

cd autogen/test/agentchat/contrib
python test_compressible_agent.py

or

cd autogen/test/agentchat/contrib
pytest test_compressible_agent.py

But now, doing so raises the error:

ModuleNotFoundError: No module named 'conftest'

Now, tests need to be run from the test root folder:

cd autogen/test
pytest agentchat/contrib/test_compressible_agent.py

This isn't a real problem, but it is a change in prior behavior, and it took me a minute to understand what was going on despite considerable prior experience with the tests.

I just logged the same issue as #1137 without realizing it was a dup. But I would give this bug a higher priority, because we have blog posts directing users to run some of these tests, and running pytest within the test folder (as described above) is a pain, and makes debugging into these tests harder. I propose a different solution in #1137.
