Fixed Issues

Manual testing scenarios

1. Create an attribute (select or multiselect) from the backend (example: attribute_code = brand_number)
2. add new Option to this attribute from the backend (12345)
3. Add new Option to this attribute by the REST API (endpoint : /V1/products/attributes/brand_number/options), json = {"option":{"label":"012345"}}
4. expected result to have two options (12345 and 012345).
