artifacts cache populated incorrectly

[BrunoBonacci]

when *print-length* is set the cache is truncated and cljr-add-project-dependency fails with the following error

cljr--get-error-value: Error in nrepl-refactor: clojure.lang.Compiler$CompilerException: Syntax error compiling at (refactor_nrepl/artifacts.clj:25:1).

as the cache will contain an ellipsis

{ ***some-content***,
"adzerk/boot-jar2bin" ("1.2.0" "1.1.1" "1.1.0" "1.0.0" "0.1.0"), ...}

This is because pr and derivates respect *print-length*

(set! *print-length* 10)
(pr-str (range 20))
;; "(0 1 2 3 4 5 6 7 8 9 ...)"

the fix for this is as follow:

(binding [*print-length* nil
            *print-level*  nil]
    (pr-str (range 20)))
;; "(0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19)"
