Nowadays lightning will initialize process group when using ddp strategy, since `TestLightningTrainNet` does a training with ddp strategy (https://fburl.com/code/a9yp0kzy), the process group ended up initialized after running the test. However there're other tests that will also set up ddp and thus expect non-initialized process group, this is not a problem on sandcastle since the tests run separately, however in OSS env, the tests are running together, so the error happens (eg. https://github.com/facebookresearch/d2go/runs/5668912203?check_suite_focus=true).

This diff adds a clean up step in `TestLightningTrainNet`.

* We have an internal dependency:
```
d2go/export/logfiledb.py", line 8, in <module>
    from mobile_cv.torch.utils_caffe2.ws_utils import ScopedWS
    ModuleNotFoundError: No module named 'mobile_cv.torch'
```
This cause the failure of unittest on GitHub
https://github.com/facebookresearch/d2go/pull/58/checks?check_run_id=2471727763

* use python 3.8 because another unittest failure on github ci
