Bug #13325: Block is not passed to Symbol proc if using refinements

----------------------------------------
The following code raises a `LocalJumpError` at the last line on 2.4 and trunk.
2.3 and earlier work fine.

```ruby
module M
  refine String do # or any class
  end
end
class C
  def call(a, x, &b)
    b.call(a, &x)
  end
end
o = C.new
x = ->(z){p z}
o.call(42, x, &:tap) #=> 42
using M
o.call(42, x, &:tap) #=> LocalJumpError
```
