ob-core: tangle check LOB after current buffer

* lisp/ob-core.el (org-babel-expand-noweb-references): Fix order when
searching for named babel blocks so that blocks in the current buffer
are always found first. This fixes a bug where stale versions of
blocks that have been ingested into the library of babel were being
preferentially tangled instead of newly modified versions from the
current buffer.
