[Tile-serving] [osm2pgsql-dev/osm2pgsql] `object:as_multipolygon()` does not take `object.members` into account. (Issue #2098)

[Christopher Kwiatkowski]

The following code removes members from object.members that have a role other than 'inner' or 'outer'.

```lua
function osm2pgsql.process_relation(object)
    if object.tags.type == 'boundary' and object.tags.boundary == 'religious_administration' and object.tags.admin_level == '10' then
        for i = #object.members, 1, -1 do
            if object.members[i].role ~= "inner" and object.members[i].role ~= "outer" then
              table.remove(object.members, i)
            end
        end

        local mp = object:as_multipolygon()
        
        parishes:insert{
            name = object.tags.name,
            geom = mp
        }
    end
end
```

However, although `object.members` only contains objects from which a boundary should be created `object:as_multipolygon()` takes into account all members, even removed ones.
