Something goes wrong in Node 0.12.14

[sp00x]

Not sure what's going on, but with node 0.12.14 this blows up:

My configuration:

        this._queueStates = StateMachine

            .configure()

                .initialState('idle')

                    .onEnter(() => {
                        if (this._queue.length > 0) this._queueStates.handle('enqueue');
                    })

                    .on('enqueue').transitionTo('process')

                .state('process')

                    .onEnter(() => {
                        this._processNextQueuedJob()
                    })

                    .on('idle').transitionTo('idle')

                .global()
                    .onStateEnter((state: string) => this._log.info(`QUEUE: Entering state ${state}`))
                    .onUnhandledEvent((event: string, state: string) => this._log.info(`QUEUE: Unhandled event '${event}' in state '${state}.'`))

            .start();

Then I enqueue something and tell the SM to "enqueue":

        this._queue.push(qj);
        this._queueStates.handle('enqueue');

and BOOM!

TypeError: undefined is not a function

Works fine in Node 4.4.5

(Just switching versions using nodist)

Apprently this is within selectTransition() where the "transitions" object is JSON.stringify(transitions) -> "[{"targetState":"process","isInternal":false,"actions":[],"condition":null}]" which does not have any find() method so this blows up trying to call "undefined";

return transitions.find(function (t) {
        return !t.condition || t.condition(context);
      });

(And why am I using 0.12.14? Well.. long story)

Fixed in v0.4.5. Thank you for digging into this!
