[JsonSchema] Property nullable or reference an object

[Jibbarth]

Jane version(s) affected: 6.0.2

Description
For a given json-schema, I have a property that can be null or reference an other object.

The code generated add MyObject|null in phpdoc, but not in typehint for function : ->getProp(): MyObject (instead of ->getProp(): ?MyObject

How to reproduce

Reproduced with this json-schema

{
    "id": "Test",
    "type": "object",
    "properties": {
        "id": {
            "oneOf": [
                {"type": "null"},
                {"$ref": "#/definitions/id"}
            ]
        }
    },
    "definitions": {
        "id": {
            "properties": {
                "uuid": {
                    "type": "string"
                }
            },
            "type": "object"
        }
    }
}

Additional context

Note, I also tested with following JSON

{
    "id": "Test",
    "type": "object",
    "properties": {
        "id": {
            "type": ["object", "null"],
            "allOf": [
                {"$ref": "#/definitions/id"}
            ]
        }
    },
    "definitions": {
        "id": {
            "properties": {
                "uuid": {
                    "type": "string"
                }
            },
            "type": "object"
        }
    }
}

For getter and setter in my Test model, it works :

    /**
     * @return TestId|null
     */
    public function getId() : ?TestId
    {
        return $this->id;
    }
    /**
     * @param TestId|null $id
     *
     * @return self
     */
    public function setId(?TestId $id) : self
    {
        $this->id = $id;
        return $this;
    }

But I have two model generated for Id, a TestId and a Id.
I would expect that only generate the Id one.

Thank in advance 🙂
