test/integration/jw-pkg -> test/integration/jw_pkg

The mypy module names of the test tree derive from the full path, anchored
by the top-level test/__init__.py, but a file below a path component that
is not a valid identifier - the dashes in jw-pkg - falls back to the bare
file name, so two same-named test.py drivers collide (the duplicate module
error that drove the runme.py and main.py renames).

Rename the directory a sane Python name - jw_pkg, that's the better fix.
Then name the driver test.py like all the others for consistency.
