[openstreetmap-website] API threw unexpected NoMethodError exception: undefined method `visible?' for nil:NilClass (#654)

[Shaun McDonald]

When using extracts I make the following change to the rails code, which means that relation won't be guaranteed to be valid. It's great, but for some purposes it'll work:

```
@@ -137,7 +137,7 @@ def to_xml_node(visible_members = nil, changeset_cache = {}, user_display_name_c
          end
        else
          # otherwise, manually go to the db to check things
 -        if member.member.visible?
 +        if member.member && member.member.visible?
            p=1
          end
        end
```
