Fully qualify clojure-complete dep to fix #1480

Here's one way to fix #1480 and I believe it's sufficient since the read-profiles initialization that fixed #1407 seems to ensure that any redundant non-group-qualified deps merged from multiple profiles won't result in redundant entries in the deps list, which seems to be the situation causing the NPE in exclusion-for-range. I had a hard time coming up with a test for this, btw, but it's easy enough to reproduce. Just create a new app and add a dep on clojure-complete to project.clj. You'll see two of them in the output of 'lein pprint :dependencies' and the NPE from 'lein deps :tree'
