overwrite not working on client.uploadFile

[mautematico]

Take this sample code:

const WordPress = require( "wordpress" );
const fs = require('fs');

const client = WordPress.createClient({
	url:		"url",
	username:	"username",
	password:	"password"
});

let file = fs.readFileSync(`/tmp/16508471_379760699056052_625556649633729067_n.jpg`);

let uploadOptions = {
	name: '16508471_379760699056052_625556649633729067_n.jpg',
        type: 'image/jpeg',
	bits: file,
    overwrite: true
};

client.uploadFile(uploadOptions, function (error, fileData) {
    console.log(fileData.attachment_id); //new ID on every upload
    console.log(fileData.metadata.file); //new file path (appending -number) on every upload
    console.log(fileData.file); //same as uploadOptions.name
});

uploadOptions.overwrite is true. Anyway, a new (duplicated) file will be created on every run.
