Autofocus broken for form

[asvae]

Vuestic-ui version: 1.7.6

UPD: I fixed all other form tests, and all methods are actually operational except for autofocus. So probably not something serious.

Right now autofocus doesn't work in very problematic way (I'm worried we broke form severely). The way form works is that every form element inside of it registers itself as child on Form (to my knowledge).
When I checked - va-input item was not even registered. So I'm seeing several levels of problems here.
I commented test for now, idea is to fix and reenable it in context of this issue.

Here's what I think we should do:

• Check all form elements are registered properly in form (maybe even in context of Polish: va-form #3765).
• Check autofocus works properly.

I tested on this story, but problem is wider than that.
