Respect provide from parentComponent

[xanf]

Instead of replacing parentComponent provide - merge it, so we can provide values in parentComponent section of config

Fixes #1262

Hey @xanf, thanks for picking up another PR 💯. Unfortunately, the 3-4 of the specs are currently failing. Do you have time to take a look at the branch and work through the error message? Cheers.

[xanf]

@JessicaSachs Sure, I'll update this one this week

Hi @xanf! any chance you could take a look at this? :)

[jdmerinor]

I'm facing this same issue :( Is there any progress with this guy?

[lmiller1990]

I don't thnk so. @jdmerinor are you interested in picking this one up by any chance? I have a bunch of other things I need to work (v3 integration, v1 release...)

Everything is passing locally for me 🤔

I will resolve the conflicts and run the test on CI again.

Ok, code is fine - just one of the older versions of Vue has some compat issues with 2.1x. For some reason this is breaking setMethods on shallowMount in 2.1... wtf?

vue-test-utils/test/specs/wrapper/setMethods.spec.js

Line 22 in a4cbe93

it('should replace methods when tied to an event', () => {

fails ONLY only for Vue 2.1 - seems no have no relation to the code changes here though?

[lmiller1990]

Ok so oddly enough this

is the problem 🤔

[lmiller1990]

Passing!

Thanks for the contribution @xanf !
