Fixes env wrapper tests timeout and disables importer tests (#181)

# Description

This PR fixes a few of the environment wrapper tests that were
previously hanging on exit, causing timeout failures. In addition, URDF
and MJCF importer tests have been disabled for now until we update the
importer wrappers to support the latest changes in Isaac Sim 4.5.

## Type of change

<!-- As you go through the list, delete the ones that are not
applicable. -->

- Bug fix (non-breaking change which fixes an issue)
