Fix test_pydsl on Windows

Fixes an issue with the test_pydsl test on Windows

This test has a hardcoded path to `/tmp` which doesn't exist by default
on Windows. This PR adds a setUp function to the class which adds that
directory on Windows and removes it after the test run. As a result it
is now a destructive test.
