Calls to trait _constructors_ emmited

[DarkDimius]

trait A
object B extends A

  public B$();
    Code:
       0: aload_0
       1: invokespecial #21                 // Method java/lang/Object."<init>":()V
       4: aload_0
       5: putstatic     #13                 // Field MODULE$:LB$;
       8: aload_0
       9: invokespecial #22                 // Method A."<init>":()V
      12: return

Trees seem to originate from constructors phase
