Resolve warning message with test

[yangwooseong]

Summary

• yarn test 혹은 yarn update-snapshot 실행시 다음과 같은 에러 메시지가 나와서 불필요한 로그가 찍힙니다.

    console.error
      Warning: An update to FeatureProvider inside a test was not wrapped in act(...).
      
      When testing, code that causes React state updates should be wrapped into act(...):
      
      act(() => {
        /* fire events that update state */
      });
      /* assert on the output */
      
      This ensures that you're testing the behavior the user would see in the browser. Learn more at https://reactjs.org/link/wrap-tests-with-act

• 이런 에러가 안나오게 적절히 test.tsx에 있는 render에 act를 감싸면 좋겠습니다.

추가)

위 warning은 FeatureProvider 안에서 if (!features) 를 if (!features.length) 로 변경하면 더이상 안뜨는 것을 확인했으나 다른 warning 도 있어서 같이 해결하면 좋을 듯 합니다

Warning: Function components cannot be given refs. Attempts to access this ref will fail. Did you mean to use React.forwardRef()? (CheckableAvatar.test.tsx) 

Warning: React does not recognize the `hasError` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `haserror` instead. If you accidentally passed it from a parent component, remove it from the DOM element. (Switch.test.tsx)
