[PHP] Namespace missing for AllOf, OneOf Models

Expecting the package namespace on $swaggerTypes and $swaggerModelName but it's missing for AllOf, OneOf references.

    protected static $swaggerTypes = [
        'date_restriction_ref' => '\MyApp\Model\DateRestrictionType',
        'date_restriction_type' => 'AllOfSpecialDateRestrictionType'
    ];

    protected static $swaggerModelName = 'AllOfSpecialDateRestrictionType';

Command line used for generation

docker run -it -v $(pwd):/opt/gen swaggerapi/swagger-codegen-cli-v3:latest generate --invoker-package MyApp --model-package "Model" --api-package "Api" -i /opt/gen/spec.yaml -l php -o /opt/gen/client

Steps to reproduce

Generate using above yaml and command. Note in AllOfSpecialDateRestrictionType.php and Special.php class names are missing the namespace

Generate the PHP client from the supplied OpenAPI YAML using the documented Docker command, then inspect AllOfSpecialDateRestrictionType.php and Special.php. Compare the names in $swaggerTypes and $swaggerModelName with the namespaced DateRestrictionType reference; done means AllOf and OneOf model references include the package namespace.
