This commit attempts to uniquely identify the temporary files and directories that are created during test runs. Where it was a quick fix, this commit also removes the temporary files and directories. There are still a ton of temporary files due to calls to .isolated_environment in the tests without an easy API an easy way to provide a closer to that function.
