[FIX] delivery : removed service from rule-based delivery quantity

Current behaviour :
Product of type service are accounted for when computing the quantity, weight and volume metrics used in the price computation of rule based delivery.

Planned behaviour :
Service-typed product should be excluded from such computations.
