Calling function returned from setupTest (which calls testEnv.Clean) in
a defer block inside a test that spawns parallel subtests caused the
cleanup function to be called before any of the subtest did anything.
Change the defer expressions to use `t.Cleanup` instead to call it only
after all subtests have also finished.
This only changes tests which have parallel subtests.

Arbitrary here does not include '', best to catch that one early as it's
almost certainly a mistake (possibly an attempt to pass a POSIX path
through this API)

Since this function is about to get more complicated, and change
behaviour, this establishes tests for the existing implementation.
