Convert generated id value to its PHP representation.

[renan]

This makes it possible for post-insert ids to be converted into a custom object as it happens for any other identity strategy.

According to the conversion rules of a specific DBAL mapping type.

@renan I'm not sure what's @Ocramius opinion here but I'd say that I don't think that the ORM should be responsible for that.

Auto generated ids are DB-dependent and wouldn't make sense to have them converted to custom objects. IMHO it's an edge case and if you really need/want to do that you can override ClassMetadata#setIdentifierValues() and do the conversion there.

[renan]

The ORM/DBAL offers a feature that can convert any given column to a different, including custom, object type. Said feature is documented here.

Currently loading/hydrating an entity that have a custom object type mapped for an auto-generated id will work as expected: converting any value to the mapped type.
What is missing is converting such value to the mapped type after a given entity is newly persisted. Again, saving an existing entity, or loading the entity, will also work as expected.

Hence I respectfully disagree, and argue this might even be a bug.

This does indeed look like a bug. Can't check the code right now, but labeling it.

@renan this was handled in #6152. Tests from here were ported there as well, thanks!
