… short stack traces (< 3 StackElements). Fixes mmcgrana/clj-stacktrace#25 and mmcgrana/clj-stacktrace#26

…ms for the cause

Need to wait for a full version bump to do this.

This reverts commit f28bb79.

When using aleph in combination with ring's wrap-stacktrace, certain
exceptions are silently swallowed by the server.  I traced this down
to clojure-ns raising a null pointer exception for the class-name
"lamina.core.observable.ConstantObservable", which is a defrecord.

This changes clojure-ns to return "lamina.core.observable" as the ns.
clojure-fn is unchanged and returns the full string, which is probably
wrong.
