mocked no longer works for jest 27.1 with isolateModules

[rburgst]

🐛 Bug Report

after upgrading from jest 27.0.6 to 27.2.0 (also fails with 27.1.1) the following code no longer invokes the mocked function

import { mocked } from "ts-jest/utils";
import * as config from "../config";

jest.mock("../config");

  it("should be able to override getBoolean", () => {
    const configGetMock = mocked(config.getBoolean).mockImplementation(() => {
      console.log("called mock");
      return true;
    });

    jest.isolateModules(() => {
      require("../uses-config");
    });

    expect(configGetMock).toBeCalledTimes(1);
  });

To Reproduce

see https://github.com/rburgst/ts-jest-27.1

Steps to reproduce the behavior:

just check out the repo and run

yarn install
yarn test

Expected behavior

if you load a file in the test using jest.isolateModules then as of jest 27.1.0 this no longer works together with a mocked method.
