Bug#1014689: leiningen-clojure breaks cljx-clojure autopkgtest: artifact nrepl:nrepl:jar:0.9.0 has not been downloaded

[Louis-Philippe Véronneau]

The autopkgtests pass locally, but britney is stuck in a loop where:

* leiningen-clojure 2.9.1-6 can't migrate because it breaks the 
cljx-clojure autopkgtest
* nrepl-clojure 0.9.0-1 can't migrate because it breaks the cljx-clojure 
autopkgtest
* leiningen-clojure 2.9.1-6 needs nrepl-clojure 0.9.0-1
* the cljx-clojure autopkgtest runs with either leiningen-clojure 
2.9.1-6 or nrepl-clojure 0.9.0-1, but never with both.

In leiningen-clojure 2.9.1-7 I tightened the versioned dependency on 
nrepl-clojure. Hopefully, this should fix the problem.

Waiting it to build and for debci to run to close this bug.
