Nullable Product Attributes

[MoritzRS]

Actual Behavior

Product Model (src/app/core/models/product/product.model.ts) specifies a property named attributes as a non nullable array.
In a customer project it turned out that the property is actually still nullable.
This causes and might cause problems because of the assumption that the property is an array and not nullable.

Expected Behavior

Either the type annotation indicates a nullable property type or the mapping is adjusted so the property really is non nullable.
