Master variant may be deleted (i.e. when the product is deleted) which would make AR’s default finder return nil. This is a stopgap for that little problem.

#variants_and_option_values(current_currency = nil) ⇒ Object

Suitable for displaying only variants that has at least one option value. There may be scenarios where an option type is removed and along with it all option values. At that point all variants associated with only those values should not be displayed to frontend users. Otherwise it breaks the idea of having variants
