Nested types in inheritance are not converted properly

[paulirwin]

If you're converting a type that inherits/extends nested types, the declaring type is left off of the conversion.

Example input:

public class CachedFeatureGeneratorFactory
    extends GeneratorFactory.AbstractXmlFeatureGeneratorFactory
    implements GeneratorFactory.XmlFeatureGeneratorFactory {

Current output:

public class CachedFeatureGeneratorFactory : AbstractXmlFeatureGeneratorFactory, XmlFeatureGeneratorFactory

Expected output:

public class CachedFeatureGeneratorFactory : GeneratorFactory.AbstractXmlFeatureGeneratorFactory, GeneratorFactory.XmlFeatureGeneratorFactory
