Fixes crash when setting selectionColor on old android devices

[jeremistadler]

Setting selectionColor for TextInput crashes on sdk version 19

This just bails out instead of crashing.

Test plan

Start an emulator with android sdk 19

import React, { Component } from 'react';
import { TextInput } from 'react-native';
export default class App extends Component {
  render() {
    return (
      <TextInput
        value="hello"
        selectionColor="#aabbcc"
        style={{margin: 40}}
      />
    );
  }
}

Nit: put return on new line with curly braces to match code style.

Actually, it was fixed in #14789.
