[ember-routing-bound-action-name] Quoteless actions in controller cause Uncaught Error

[inDream]

If the action is defined in controller but not controller.actions,
Uncaught Error: Nothing handled the action 'function ...' will appear.

Demo: http://jsfiddle.net/indream/Fu5uG/

This can fix by replace https://github.com/emberjs/ember.js/blob/master/packages/ember-routing/lib/helpers/action.js#L92 with
if(typeof actionName === 'undefined' || typeof actionName === 'function') {

Reference: #3936

@inDream - Thank you for reporting! Should be fixed in #4336.
