allowConsoleError should capture async errors

The following code illustrate the problem, where we expect a console error, but it actually might leak to outside of this test.

```
it('abc', () => {
  allowConsoleError(() => {
     asyncFuncThatPrintsConsoleError();
  });
})

function asyncFuncThatPrintsConsoleError() {
  setTimeout(() => {
     console.error('errr!!!')
  }, 1);
}
```
