tests(t004): fix small issue that only occurs on Windows (#695)

t004 fails on Windows in comparing a data frame to a numpy array.  The i, j, k columns from the data frame were upgraded to long ints.  Apparently the default int on Windows is different from the default on mac/linux, so test failures don't show up there.

Also stop versioning several shapefiles that are recreated with every test run.
