Add missing member fix should work for missing function

[ghost]

TypeScript Version: 3.1.0-dev.20180804

Code

class C {}
new C().m();

f();

namespace N { export const x = 0; }
N.f();

import * as m from "./mod";
m.f();

Expected behavior:

Codefix for both m() and for every f().

Actual behavior:

Codefix for only m().

Duplicate of my issue:

My issue was closed as "* out-of-scope", and here someone is doing it (almost completely).

@mjbvz I am glad that this has been realized.
But maybe the original needs to be marked?
