Cyclic dependency error when using concat

[aaronabf]

There is a regression of #1423 when Yup was upgraded from 0.32.11 to 1.0.0 in which when using concat on an object schema with a dependency list it seems to be ignored.

To reproduce, simply go to the Code Sandbox link provided in the referenced issue and update the Yup version:

1. Visit https://codesandbox.io/s/yup-concat-order-pemfy?file=/src/index.js
2. Update yup to 0.32.11 and observe there is no issue
3. Update yup to 1.0.2 and observe the original issue surfaces: "Cyclic dependency"

You can also observe the issue when using a more minimal example than the Code Sandbox example:

import * as Yup from "yup";

const a = Yup.object().shape(
  {
    a1: Yup.string().when("a2", {
      is: undefined,
      then: Yup.string().required()
    }),
    a2: Yup.string().when("a1", {
      is: undefined,
      then: Yup.string().required()
    })
  },
  [["a1", "a2"]]
);

// works
const b = Yup.object().shape({
  b1: Yup.string().required(),
});

// doesn't work
const c = b
  .concat(a);
