TextInput does refresh 'applyTextInputStyles' on update

[pglockwo]

'applyTextInputStyles' is only called on component did mount, when an error is applied to the component after the initial mount the error state CSS is not applied.

componentDidMount() {
this.applyTextInputStyles();
}

Maybe this needs adding

componentDidUpdate() {
// check here to see if the error state has changed before applying the styles
this.applyTextInputStyles();
}
