tests: restore previous fix for date ambiguity in cvs test 017ab404e588 changed some sleeps after cvs update to sleeps before commit. I don't know why that should work, but I have a machine where it doesn't work. Commits regularly fails becuase cvs doesn't notice that a file has been changed. Restoring the previous sleep between the update and the edit makes cvs notice the change.
