osm.conveyal.com doesn't write relations

[buma]

According to #21 relations should be outputted.

I tested locally with own copy of osm-lib. I loaded Washington DC PBF and when I did wget http://localhost:9002/tile/38.887024,-77.040253,38.918017,-77.01004.pbf I got file with relations. But same request on osm.conveyal.com outputs file with no relations.

The only thing I changed locally is commented starting of update thread since I have old PBF file and I don't want to wait for all updates to be applied.
