MMRecordAttributeAlternateNameKey is ignored if the value can be found using the default key

[sstigler]

For example:

{id: 123, name: "outer", inner: { id: 456, name: "inner" } }

Although MMRecord only provides default access to the outer dictionary, I would really like both the name and ID of the object represented by the inner dictionary. While MMRecordAttributeAlternateNameKey will work as expected for inner.name, if I specify inner.id I will get a value of 123 instead of 456.
