test(fireEvent): Add expected behavior for blur/focus in React #757

What:

Add expected behavior for blur and focus bubbling in React. This is different than native DOM events where blur and focus do not bubble

Why:

Got messaged by core members that they might start listening to focusin/focusout instead which would cause our current fireEvent.focus implementation to not register React focus events. We should also fire focusin/focusout once they start doing that (i.e. react@next starts breaking the build) which is similar to how we handle mouseEnter/mouseLeave.

Ideally we'd get everybody on board to using .focus() and blur() instead but that would only work with [email protected] or a browser which is less than ideal.

How:

Assert on invocation of event handlers for bubbled events
