Allow to specify one handler for multiple events in the event bus reciever

Allows to define set the same handler for multiple events with a simple syntax:

```
this.eventBusReceiver.onEvents([
      "pickup request refused by driver",
      "pickup request could not be accepted by driver",
      "pickup request could not be canceled by driver",
      "pickup request could not be refused by driver",
      "pickup request could not be started by driver",
      "pickup request could not be stopped by driver"
    ], function(event, callback) { /* Do something */});
```
