react-hook-form

🥂 properly fixed isValid formState with schema and build-in validation. (sorry this is a long dragged issue)

• proper tracking with isValid during register phase
• tracking when input removed
• added automation tests

📖 Story: The challenge for me was to track form valid state during render phase, because RHF embrace uncontrolled inputs, so users can provide default value during render phase and we need to track valid on the fly, and this took me quite few attend to get it right.
