org-batch-test-init: Remove dead code

* testing/org-batch-test-init.el (lambda): Remove the code that has
never been working.  One could still rewrite the code using
`autoloadp', but it would break things terribly and should not be
needed as autoload does not need to be updated after changing the
`load-path'.  See
