Cannot filter on derived properties - startTypeFilter in MemberImpl is ignored

According to Addressing Derived Types user should be able to filter on derived field
Example:
http://host/service/Customers?$filter=Model.VipCustomer/PercentageOfVipPromotionProductsOrdered gt 80

Information about type (e.g. Model.VipCustomer) is stored in field startTypeFilter(in MemberImpl), but it is not passed to ExpressionVisitor in accept method. ExpressionVisitor get only path. startTypeFilter is ignored, so it can't be used in visitMember method.

Suggested changes - patch in attachment.
