Make test_root_static_path more robust.

Always convert `__file__` to an absolute path (this is already
guaranteed in Python 3.4+, but in older versions it would sometimes be
relative). Encode the path so the test can pass when run from a
directory containing spaces or other special characters.

Fixes #1565
