Validation error for min-max-n-peers for flux policy is not printed correctly.

[kamituel]

The following catalog entry:

{:onyx/name ::compute-average
 :onyx/type :function
 :onyx/batch-size batch-size
 :onyx/batch-timeout batch-timeout
 :onyx/group-by-fn ::some-grouping-fn
 :onyx/flux-policy :kill}

fails validation when submitting a job. This is printed in the REPL:

------ Onyx Job Error ----- 
There was a validation error in your catalog for key 9 

{:onyx/name :example/compute-average 
 :onyx/fn :clojure.core/identity 
 :onyx/type :function 
 :onyx/batch-size 5 
 :onyx/batch-timeout 50 
 :onyx/group-by-fn :nexample/some-grouping-fn 
 :onyx/flux-policy :kill } 

------

The true reason it failed is revealed when validating by hand:

(require '[onyx.schema :refer [Job]])
(require '[schema.core :as schema])
(schema/validate Job job-map)

clojure.lang.ExceptionInfo: Value does not match schema: {:catalog [nil nil nil nil nil nil nil nil nil (not (valid-flux-policy-min-max-n-peers a-clojure.lang.PersistentArrayMap)) nil]}

So for this particular misconfiguration, the validation error is getting swallowed somewhere.
