fix stubbing issues and prep for release 0.9.1 for datafile manager and event processor packages (#712)

## Summary
Upgrading to latest typescript version is causing stubbing issues and failing some unit tests. Downgrading the typescript version to `3.8.x` temporarily to fix this. Also updated the version of `logging` to `0.3.1` which downgrades typescript version in that package

## Test plan
- Manually tested thoroughly.
-  All existing tests pass
