Enable i18n for placeholders and FieldDecorator messages among others

Version

2.9.2

Environment

OS X, Chrome, React Intl

Reproduction link

https://github.com/enzolutions/antd-intl-demo

Steps to reproduce

$ git clone [e-mail]:enzolutions/antd-intl-demo.git
$ npm run dev
$ npm run start

Open your browser at page http://127.0.0.1:8000/

You could see the input have a [object object] text inside as you can see in the following image

What is expected?

Field decorator message and input placeholder could be translated in the same way the Form Item label is translated

What is actually happening?

The translation object is not processed and the object type is rendered as string

---

I tried also with another i18n library https://github.com/vazco/meteor-universe-i18n with the same behavior.

The Antd library must be objected to enable those elements and similar accept object to enable a full translation

It is not a antd related problem.

You can’t use <FormattedMessage /> in native input placeholder either, which only accept string type value.

<input placeholder={<FormattedMessage id="xxx" />} /> // broken
<input placeholder={intl.formatMessage({ id: 'xxx' })} /> // good

import React from 'react';
import { injectIntl } from 'react-intl';
import { Input} from "antd";

const Input18 = ({ intl}) => {
    console.log(intl);
    return <Input type="text" placeholder={intl.formatMessage({id: 'email'})}/>
};

export default injectIntl(Input18)

import Input18 from './input';

       <Input18
                    prefix={<UserOutlined/>}
                    size="large"
      

                />
