It seems that #8846 accidentally introduced a bug where pruning on a union type containing services that are implemented by the same service throws an error.

Previously, the following code:

trait Foo
trait Bar
final class FooBar extends Foo, Bar

@main def broken =
  ZEnvironment(new FooBar).prune[Foo & Bar]

throws this error:

java.lang.Error: Defect in zio.ZEnvironment: HashSet(Bar) statically known to be contained within the environment are missing
