Tries to find an entity with the same PK values as passed in. The PK values have to be in the same order as they appear in the constructor of the entity. If an entity in the context has the same PK values, that entity is returned, otherwise a new entity is returned, created with the factory passed in, with its PK values initialized, though not fetched.
