Fix failing Mononoke Git integration test

Summary: When `test-mononoke-git-server-push-with-fb-product-log.t` was created, the underlying git client used in integration test would auto populate the header `x-fb-product-log`. However, at one point that stopped being true which led to this integration test consistently failing. While this problem gets fixed in production, this diff atleast fixes the integration test
