common.wrapError being used incorrectly?

[davewasmer]

Looks like common.wrapError is being used incorrectly in notification_bus around line 170:

    this.dataClient.on('taskError', function (evt) {
      common.wrapError(evt);
    });
    this.pubClient.on('taskError', function (evt) {
      common.wrapError(evt);
    });
    this.subClient.on('taskError', function (evt) {
      common.wrapError(evt);
    });

common.wrapError returns a function, so these listeners won't do anything. It seems like wrapError is designed to "pipe" an error event from one emitter to another, and I don't know which emitter these listeners are attempting to pipe to.
