Always store selector in Wrapper created by wrapper.find(...)

What problem does this feature solve?

When using wrapper.find(...), the returned new wrapper only knows the selector if nothing was found. This makes it difficult to debug tests with dynamic selectors and to create custom matchers like expect(wrapper.find('.something')).toExist().

What does the proposed API look like?

Make Wrapper always have a selector property when created with .find(...)—not only ErrorWrapper (

vue-test-utils/packages/test-utils/src/error-wrapper.js

Line 9 in 36adbf3

this.selector = selector

).

This is a great idea :)

Would you like to implement it @gitlab-winnie ?

I can't make any Promise yet but have to await my workload for the next month. Definitely interested in getting my feet wet at the Vue test utils beach though. 🏖

I started working on this in #1248.
