cy.type shouldn't perform actionability if subject is the currently focused element

[kuceb]

If the subject to cy.type is focused, we shouldn't perform actionability because the user is already able to start sending keys to the element without needing to click/tab into it.

This allows apps to call .focus() on an otherwise covered/animating element and allow cypress to still type into it, just as a user would

The code for this is done in cypress-io/cypress#2982, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
