Fix wrong file names in itk_python_add_test

[acoussat]

Fixes a bug introduced by #80.

I think this mistake went unnoticed because these two tests are never ran by the CI. As far as I remember, either we run ctest with ITK_WRAP_PYTHON=OFF or we run pytest with ITK_WRAP_PYTHON=ON, but we never run ctest with ITK_WRAP_PYTHON=ON. Is there a similar issue in RTK, which also uses itk_python_add_test? @axel-grc

I'm a bit confused as it does not seem related to the current PR, and I cannot reproduce it on my machine. @axel-grc any idea?

Should be fixed by #83 indeed
