Makes map service check style compliant

I would clean this up like this:

```
 public void onReplicationEvent(WanReplicationEvent replicationEvent) {
      Object eventObject = replicationEvent.getEventObject();
      if(ventObject instanceof MapReplicationUpdate) {
           onMapReplicateUpdate((MapReplicationUpdate)eventObject)
      }else if(MapReplicationRemove blabla) {
           onMapReplicationRemove((MapReplicationRemove)eventObject)
      } else{ ...}
 }
```

This reduces the method length and gives each method a better defined responsibility. Apart from that it makes the code a lot easier to read.
