There is a warning message when using upload behavior on a model with composite primary key

The file is uploaded correctly but with a warning message. If I remove a composite primary key and make it a single primary key, the warning message is gone.

This is a configuration of my ModelTable.

$this->setPrimaryKey(['id', 'member_id']);

$this->addBehavior('Josegonzalez/Upload.Upload', [
       'logo' => [
                'fields' => [
                    'dir' => 'logo_dir',
                    'size' => 'logo_size',
                    'type' => 'logo_type'
                ],
                'nameCallback' => function ($table, $entity, $data, $field, $settings) {
                    return strtolower($data['name']);
                },
                'keepFilesOnDelete' => false
       ]
]);

@melbreaker could you test #515 ?
