fix(Dropdown): handle "onClick" on options

[layershifter]

Fixes #4315.

This PR fixes scenario when options contain an item that has onClick:

function App() {
  return (
    <Dropdown
      options={[
        { key: "foo", text: "foo", value: "foo" },
        {
          key: "bar",
          text: "bar",
          value: "bar",
          onClick: () => console.log("Hello!")
        }
      ]}
    />
  );
}
