Description

The Olingo4Consumer when filtered using the already-seen property, is checked for empty EntitySets and returns 0. This return value ensures that unless consumer.sendEmptyMessageWhenIdle = true, no empty messages are generated.
However, this behaviour is not consistent when a key predicate is used. In this case, an entity is returned which is then filtered to null. This is not handled and an empty message is transmitted with a null body.
