enhance: Schemas with no entities should not infer

[ntucker]

Motivation

Better support simple response endpoints.

With no entities, denormalization is pointless. However, what's worse is since it found all the entities it needed (since it didn't need any) - it will attempt to infer results. Inferring results is non-nonsensical with no entities as it would just be returning the schema.

Solution

Add simple schemaHasEntity() algorithm to determine whether a schema has entities. When it doesn't we short-circuit the de-normalization computation.
