Default behavior of promotion engine Evaluate extension methods returns only fulfilled promotions

Description

When calling one of the IPromotionEngineExtensions overloads for Evaluate that doesn't take a RequestFulfillmentStatus parameter, it defaults to Fulfilled only.

This is most likely an unexpected behavior considering the expected use-case for Evaluate: given a product listing, you want to check which products have an entry-level promotion. If quantity for the condition is > 1, the promotion is never found. By passing in PartiallyFulfilled as well, all matching promotions are discovered.
