TODO: This method assumes that $id is a valid PHP identifier for the
document class. If the class expects its database identifier to be a
MongoId, and an incompatible $id is registered (e.g. an integer), the
document identifiers map will become inconsistent with the identity map.
In the future, we may want to round-trip $id through a PHP and database
conversion and throw an exception if it's inconsistent.
