[PATCH] Fix issue with ob-clojure not returning output

The attached patch is a simple fix for the problem with ob-clojure using an
incorrect cider-current-session call instead of cider-current-ns. For
background on the issue see
https://emacs.stackexchange.com/questions/30857/clojure-code-evaluation-in-org-mode-produces-no-output/31169#31169


Not 100% convinced that the optional namespace argument should even be
included - it really doesn't seem to do anything. However, leaving it in
seemed like the minimal change needed.  Have tested it and at least I now
get data back from evaluation of clojure code blocks where previously, you
only got the message "block processed with no output".
