Qualifiers do not work in subcomponent factory

[matejdro]

Following code does not compile:

class MyScope
class SubScope

@Qualifier
annotation class QualifiedString

@Component
@MergeComponent(MyScope::class)
@SingleIn(MyScope::class)
interface MainComponent : MainComponentMerged {
}

@ContributesSubcomponent(SubScope::class)
@SingleIn(SubScope::class)
interface RendererComponent {
   @QualifiedString
   val qualifiedString: String

   @ContributesSubcomponent.Factory(MyScope::class)
   interface Factory {
      fun createRendererComponent(@QualifiedString string: String): RendererComponent
   }
}

It complains that Cannot find an @Inject constructor or provider for: @QualifiedString String, even though that string should have been provided by the subcomponent factory. It appears that qualifier annotations get lost when component is merged.

This should work and is a gap.
