Fix test_scriptpackage with pure will power.

I really don't know why I bother; these are all generated files.
But I don't recall how to regenerate them nor how to fix the generator.

The hardest part was fixing two mutual recursive imports;
somehow changing "import foo" into "from . import foo" where
foo and bar import each other AND both are imported from __init__.py
caused things to break.  Bah.
