[TASK] Implement RuleValueList::getArrayRepresentation() (#1457)

The class has no additional properties, so this is a simple case of removing
the stub method so it inherits its parent implementation, and adding a test.

A stub exception-throwing method is added (pushed down the chain) to the
subclass `CalcRuleValueList` pending implementation.

Part of #1440.
