Not compatible with Jest's resetMocks option

[josselinbuils]

Hello,

First thank you for this great lib 😄

It seems that the way to use this library described in the documentation is not compatible with the resetMocks option of Jest.

Indeed, next/dynamic is only mocked for the first test and the real one is restored from the second test.

I don't know if it could be managed by the lib directly but it could be at least documented.

Here is a possible but quite verbose workaround:

  let MyComponent;

  beforeAll(async () => {
    let preloadAll;
    jest.isolateModules(() => {
      preloadAll = require('jest-next-dynamic');
    });
    MyComponent = require('../MyComponent').default;
    await preloadAll();
  });

I don't understand why it is working but putting this in a file referenced by setupFilesAfterEnv in the Jest config seems also to fix the issue:

jest.isolateModules(() => {
  const preloadAll = require('jest-next-dynamic');

  beforeEach(async () => {
    await preloadAll();
  });
});

The unknown thing to me is why the mock implementation is not reset between tests in these conditions as this setup file seems to be executed only once by test file.
