Ensure rc.5 doesn't break things

[lmiller1990]

Some breaking changes for us. Relevant: vuejs/core@a75b8a2

So it does, this line mainly https://github.com/vuejs/vue-test-utils-next/blob/c3e2673b3be49b6065d82aa18ab2529889698235/src/utils/find.ts#L45

We can no longer find un-named components, so this fails: https://github.com/vuejs/vue-test-utils-next/blob/c3e2673b3be49b6065d82aa18ab2529889698235/tests/findComponent.spec.ts#L85

I am not sure how to fix this yet. Or if we can.

Edit: does anyone expect this to work in the first place? "Finds a component without a name by name" seems like a strange thing to even support.

These four fail too: https://github.com/vuejs/vue-test-utils-next/blob/c3e2673b3be49b6065d82aa18ab2529889698235/tests/setValue.spec.ts#L205 for the same reason, const registry = (node.component.parent as any).components no longer exists.

Edit: fixed the mount ones, shallowMount ones still fail.

One fix for using find with shallowMount would be to require users to specify a name on their components. By adding a name to the PlainInputComponent, the test is able to pass.

@lmiller1990 I pushed a PR that should fix all the issues. See #167 when you have some time
The test has a weird name, but we try to find a component without a name based on its name in the parent registration (on Evan suggestion) ;)

It's out!
