Subject: [PATCH] fix: use `this.equals` instead of import jasmineUtils

As per the [comment](https://github.com/testing-library/jest-dom/pull/93#discussion_r282040908) by @SimenB

This will remove the direct import of jasmineUtils

`import {equals} from 'expect/build/jasmineUtils'`

and instead use `this.equals`.

Also removes the added dependency of `expect`.
