Two different Errors are considered equal

[MiniGod]

const a = new Error('a');
const b = new Error('b');

expect(Promise.reject(a)).toRejectWith(b, done);

passes although a and b are different.

The issue is that deep-equal consider them equal:

Could be fixed when inspect-js/node-deep-equal#48 gets merged.
