Using `find({ref: '...'})` to target an `Element` logs a deprecation warning

Subject of the issue

Trying to find an Element by its ref gives a deprecation warning.

Steps to reproduce

Consider this component:

<template>
  <div>
    <div ref="child" />
  </div>
</template>

If I want to find the "child" element, I'd like to be able to write:

wrapper.find({ref: 'child'})

However, if I do this, then I get a deprecation warning, because my selector isn't a DOM_SELECTOR (it's a REF_SELECTOR).

On the other hand, if I do what the deprecation warning suggests and use findComponent(), then the test fails, because findAllComponents() filters for isVueWrapper, which fails for an Element.

Expected behaviour

I should be able to use find({ref: ''}) to target an Element without a deprecation warning, or use findComponent({ref: ''}), as suggested.

Actual behaviour

I get deprecation errors in my tests.

Possible Solution

The obvious workaround is to not use a ref to target the Element, but it's not ideal, since a ref is a nice, syntactic non-style-based way of targeting an element for testing, which aligns with Vue's own syntax (as opposed to adding eg a data-test attribute or similar).

I think this may have been a regression introduced by #1910 ? That is, I think we used to be able to use findComponent({ref: ''} to find an Element (and therefore avoid the deprecation warning), but now can't...?

I'm having the same problem.
In ver 1.2.2, the tests that used to pass with wrapper.findAllComponents({ ref: 'example' }) will now fail.

@tagucch For me 1.2.2 is working but 1.3.0 is not.

I'll have a look at that issue. I had to downgrade to 1.2.2 as well to make the tests pass.
