Title: non-functional visibility check in `Relation#to_xml_node`

What's going on [here](https://github.com/openstreetmap/openstreetmap-website/blob/e64bcf335a95f7cc35cd19c190b8111c2d7b275f/app/models/relation.rb#L150)? `p` is either 0 or 1, both of which are truthy in Ruby, so the `if` block is always executed.

Do we need this check?
