Implementations not generated for abstract properties if Component superclass is a typealias

```kotlin
@Inject class Foo

interface FooComponent {
  val foo: Foo
}

typealias FooComponentTypealias = FooComponent

@Component
abstract class RealFooComponent : FooComponentTypealias
```

causes error:

```
Class 'InjectRealFooComponent' is not abstract and does not implement abstract member 'foo'.
```
