Passing null into constructor of EntityWrapper

[s4heid]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

After #318, it is no longer possible to pass null, as an argument for the Entity into the constructor of the EntityWrapper. This is because we need to retrieve the created entity.

If this breaking change was not intended, I would like to propose adding a null check.

Expected Behavior

If the Entity is null, complete the promise and respond with No Content.

Steps To Reproduce

new EntityWrapper(ENTITY_NAME, (Entity) null)

Environment

- OS: ubuntu
- Java: 11
- NeonBee: 0.0.26

Relevant log output
