Bogus EntitySetPath error

[mikepizzo]

When defining a function or an action, the optional EntitySetPath specifies the collection where any returned entities live. If the return type is a collection of entities, the EntitySetPath (if specified) must reference a collection -- if the return type is a single entity, then the path will typically be a collection but may be a singleton or single-valued containment nav prop. Currently, validating a model throws an invalid error if the return type is a single entity and the entitysetpath indicates a collection.

Assemblies affected
