fix(types): build issue with typescript undefined error (#1024)

* Update index.d.ts

enforce the ValidationArgs to have a value and force typescript not identify it as a undefined

* add T State to depend on ValidationArgs

Make ValidationArgs without parameters 
Make sure that the state has every key in the validation to ensure correct state parameters

* revert Validation Args type

* revert ValidationArgs to default
