`pool.getConnection()` not working when `returnArgumentsArray: true` is set in config

[Tawank]

If returnArgumentsArray is set in the config to true, node crashes on pool.getConnection() with an error:

Unhandled rejection TypeError: Cannot read property 'apply' of undefined

My test app:

const config = require('./config.json');
const mysql = require('promise-mysql');

const createPool = mysql.createPool({
  host: config.DB_HOST,
  user: config.DB_USER,
  password: config.DB_PASSWORD,
  database: config.DB_NAME,
  returnArgumentsArray: true, // if is set to true the pool.getConnection() does not work
});

function testTransaction() {
  createPool.then(async (pool) => {
    const connection = await pool.getConnection();
    try {
      await connection.beginTransaction();
      const result = await connection.query('SELECT 1+1');
      console.log(result);
      await connection.commit();
      await connection.release();
    } catch (e) {
      await connection.rollback();
      await connection.release();
      throw e;
    }
  });
}
testTransaction();

Thanks for this, I've just published version 4.1.3 with a fix for this.
