Creating a reponse with an empty entity gets nil as entity on sending #entity to ZnClient instance

[fortizpenaloza]

Using Zinc-REST package i tried to create a empty response like this:

ZnJSONRestCall#empyResponse

     entity := ZnEntity with: String new type: ZnMimeType applicationJson.
     ^ response := ZnResponse ok: entity

The code using it is similar to ZnExampleStorageObjectRestCall#put method.

So on a test i've this collaborations

     ...
client
    addPathSegment: '1';
    contents: data;
    put.

self assert: client isSuccess.
self assert: client entity isEmpty.
self assert: client response contentLength equals: 0.

But client entity isEmpty fails because entity is nil instead of a empty entity.

Is this the expeted behavior?

That is an optimalization: when the response is of 0 length no ZnEntity object is created. There is also #hasEntity
