fix(test): make .pth files once per session

The old way, we made and deleted .pth file around each test.  This
caused problems because pth files are written to a common location
shared by all test workers, so tests would fail because pth files were
being deleted as other workers were trying to use them.

Now we make the pth file once per session.  There's still a chance that
a worker will be using a pth file just as another worker is ending and
removing it.
