Modify macro `org-test-with-temp-text-in-file' to work on emacs 22. * testing/org-test.el:

In Emacs 22 the `kill-buffer' argument is NOT optional. This change
reflects this and allows the macro `org-test-with-temp-text-in-file'
to work in Emacs 22 for org compatibility. This fixes the test
`test-ob-lob/do-not-eval-lob-lines-in-example-blocks-on-export'
