const renderProps: ITextFieldProps = { ...this.props, componentId: this._id };

let {
    componentId = this._id
} = this.props;

const renderProps: ITextFieldProps = { ...this.props, componentId };

Sorry, I probably should've asked this question before I made the PR.
Do we want to expose the internal componentId and allow users to set it via props, or do we want to keep componentId internal and remove it from the props?

@lambertwang, I think logic written in docs doesn't need any changes

@lambertwang, and I think it's right to let developers install IDs from the elements. It can be useful for auto tests.
