Bug #13973: super_method fails on some UnboundMethods
https://bugs.ruby-lang.org/issues/13973

* Author: marcandre (Marc-Andre Lafortune)
* Status: Open
* Priority: Normal
* Assignee: nobu (Nobuyoshi Nakada)
* Target version: 2.5
* ruby -v: trunk
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
`super_method` fails to go up the ancestry chain for methods that are only defined in included modules:

~~~ ruby
module A
  def foo
  end
end

module B
  def foo
  end
end

class C
  include A
  include B
end

class D
  def foo
  end
  include A
  include B
end

C.instance_method(:foo) # => #<UnboundMethod: C(B)#foo> (ok)
C.instance_method(:foo).super_method # => nil (wrong, should be <UnboundMethod: <something>(A)#foo>)
C.new.method(:foo).super_method # => #<Method: Object(A)#foo> (ok)
D.instance_method(:foo).super_method # => #<UnboundMethod: Object(B)#foo> (ok)
D.instance_method(:foo).super_method.super_method # => #<UnboundMethod: Object(A)#foo> (ok)
~~~

Note that the results for C and D's super_method differ slightly, with one outputing "C(B)" and the other "Object(B)". I don't understand why "Object" shows anywhere in my example. I would have expected the output to be "D(B)" in the later case. Should I open a different issue for this?
