Axios requests with proxy fails to redirect properly

### Summary

Axios requests with proxy fails to redirect properly, as described below:

The request:

const axios = require('axios')

axios.get('http://testapi.testdomain.com/api/articles/personal/01d76a9844ae4a919f02ddedf11a6fcc?page=2&size=10', {
  proxy: {
    host: '127.0.0.1',
    port: 1080
  }
})
.then((response) => {
  console.log(response)
})
.catch((err) => {
  console.log(err)
})

The response:

     _isRedirect: true },
  response: undefined }

Please note the error part of response at the top:

{ Error: connect ECONNREFUSED 127.0.0.1:80
    at Object.exports._errnoException (util.js:1022:11)

and the response part at the bottom:

     _currentUrl: 'http://127.0.0.1/api/articles/personal/01d76a9844ae4a919f02ddedf11a6fcc?page=2&size=10&uc_param_str=dnvebichntwidsudsvpflameefut',
     _isRedirect: true },

What I got is http://127.0.0.1/api/articles/personal/01d76a9844ae4a919f02ddedf11a6fcc?page=2&size=10&uc_param_str=dnvebichntwidsudsvpflameefut,

and what I expect should be http://testapi.testdomain.com/api/articles/personal/01d76a9844ae4a919f02ddedf11a6fcc?page=2&size=10&uc_param_str=dnvebichntwidsudsvpflameefut
