Optional property return type with a default value is nullable

[wol-soft]

Only applies if the option implicitNull is not enabled. If no default value is provided the property must be nullable (value is null if no value is provided). If implicitNull is enabled the return type must also be nullable as optional properties with this option accept null.

{
    "type": "object",
    "properties": {
        "test": {
            "type": "boolean",
            "default": false
    }
}

Expected interface:

public function getTest(): bool;

Generated interface:

public function getTest(): ?bool;
