Is this equivalent to before? It seems that before this.userInfo_.activeUser
could be null or undefined.

Modified CloudPrintInterface.search so that it can accept null or
undefined inputs, as it does this || '' step at the very beginning
of the function.

           cr.dispatchSimpleEvent(
               this, DestinationStore.EventType.DESTINATION_SEARCH_STARTED);
         }
