ClassScanner::getInterfaces() don't work correctly with Interface

[mapkuff]

short example

 Interface A {  }
 Interface B {  }
 Interface C extends A,B {  }

 $fileScanner = .....; // a file which contains Interface C
 $clazz = $fileScanner->getClasses()[0]; //which is C

 $clazz->getInterfaces(); // this line don't work correctly. It should return A and B
