Array items not being regenerated

[soup-in-boots]

When using the form generator hook with arrays, items are not updated if the form changes. This appears to be an issue with the useArrayItems hook.

[soup-in-boots]

useArrayItems' useEffect to initialize the forms was at fault. It would only run once on initialization, and any forms created in that run would essentially be static. Adding new items would create new, updated forms, but items were essentially one render behind.

Triggering the effect on every value update (the right thing) was blasting away all of the forms, causing inputs to be re-rendered and form input focus to be lost. Instead of creating all new items, the patch now iterates over the existing items, updating them if they exist and creating them if they don't.

Fixed in v1.3.2
