[Ironruby-core] Ordered active record attributes hash

Hi all,

I found the solution for this puzzle:

Active record, when you call the procedure attributes, it sorts the
attributes by key, so, by working in the following way, that works
correctly:

row.instance_variable_get(:@attributes).to_yaml

instead of

row.attributes.to_yaml

Thank you anyways

Eduardo
