jest: #5585 breaks pre-established "beforeEach" order

When introduced #5885, the order of beforeEachs was inverted. Take the following test for instance:

describe('test', () => {
  beforeEach(() => {
    console.log('BeforeEach');
  });

  it('foo', () => {
    console.log('It Foo');

    beforeEach(() => {
      console.log('BeforeEach Inline Foo');
    });
  });

  it('bar', () => {
    console.log('It Bar');

    beforeEach(() => {
      console.log('BeforeEach Inline Bar');
    });
  });
});

The order should be:

BeforeEach
It Foo
BeforeEach Inline Foo
BeforeEach
It Bar

But it is instead:

BeforeEach
It Foo
BeforeEach
BeforeEach Inline Foo
It Bar

One might argue about beforeEachs inside its, but the reality is that this is supported and the current order is altered. We need to get some sort of fix or rather revert the PR.
