fix(react-search): Restore focus to SearchBox after clear button is clicked

[emmayjiang]

Previous Behavior

When the clear button is pressed, the contents of the SearchBox is cleared but focus remains on the clear button.

New Behavior

When the clear button is pressed, the contents of the SearchBox is cleared and focus is restored to the SearchBox, so users don't have to perform an extra action to begin typing in the SearchBox again.
