Incorrect nulls

[Gemorroj]

All null values have unnecessary backslash for example 91 line:

protected $meta_data = \null;

Hello @Gemorroj! Thank you for your report. These stubs are automatically generated from WC source code. I think the generator tool puts there those backslashes. https://github.com/php-stubs/woocommerce-stubs/blob/master/composer.json#L17
