This test covers the behavior of the JSII runtimes when a method is declared to return an interface type, and returns an instance of a private (un-exported) type that implements the interface while extending an exported type. This has been seen to cause issues in the Java runtime, for example, as the JSII kernel will return an ObjID with a type fragment that refers to the exported super-class, and not the interface type.
When an un-exported type that extends an exported type is returned with an interface as the declared type, the JSII kernel used to return a ref with the FQN of the exported supertype, instead of correctly wrapping the instance in a proxy of the interface type as it should have. Fixes #302
