InMemoryProducer creates redundant EntityId properties

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run an InMemoryProducer (e.g. InMemoryProducerExample after fixing issue 68).
2. Display metadata (e.g. 
http://localhost:8887/InMemoryProducerExample.svc/$metadata).

What is the expected output? What do you see instead?
For every <EntityType> there are two <Property>s with Name="EntityId". One with 
attribute Nullable="true", one with Nullable="false".

What version of the product are you using? On what operating system?
0.5.SNAPSHOT

Please provide any additional information below.
A possible fix would be to remove the implementation for method 
getPropertyNames() in class EntityIdFunctionPropertyModelDelegate. The existing 
implementation adds the idPropertyName (which always is "EntityId") to the 
returned list of properties. I don't think that this is intended, as the 
"EntityId" property is added within InMemoryProducer.createStructuralEntities() 
and InMemoryProducer.toOEntity() before the other properties are added.
