Update README.md

[voraczech]

What: Changing documentation appropriately - shouldRenderSuggestions (should-render-suggestions) does not return true if there is 0 results.

Why: shouldRenderSuggestions shows only if there is any result but not when 0

shouldRenderSuggestions: {
      type: Function,
      required: false,
      default: (totalResults, loading) => {
        return totalResults > 0 && !loading;
      }
},

How: changing docs (rather than code)
