Enable unit tests which use argoverse

We use pip to install Argoverse in our conda environment. The Argoverse pins the numpy version to an older version ([ref](https://github.com/argoai/argoverse-api/blob/master/setup.py)). This leads to uninstall of the conda installed numpy, and leads to conflicts with other packages.

Till the argoverse numpy verion is upgraded, we have ignored 2 unit tests from our CI in #585. To close this ticket, please enable the tests in the CI.
