fix extra required attributes for variants by applying extra required attributes on item descriptor #9

extra required attributes must be added in item descriptor. Now that each template has its own descriptor, it is possible. Also, this way it is fixed the case when extra required attribute comes in a variant (added test). Also, avoid different tests to use the same descriptor instance.
