Issue: Support Array of Objects in toQueryString

Problem 🤔

Hi master Babs !
The current implementation of toQueryString doesn't handle arrays of objects in a user-friendly way.

Example 📝

const query = {
  'persons': [
    { 'id': 0, 'name': 'john' },
    { 'id': 1, 'name': 'alice' }
  ],
  'cars': [
    { 'id': 0, 'name': 'audi' },
    { 'id': 1, 'name': 'tesla' }
  ];

toQueryString(query);

Expected Result 🎯

"?cars=id:0,name:audi,id:1,name:tesla&persons=id:0,name:john,id:1,name:alice"

Actual Result 🤯

"?cars=[object Object],[object Object]&persons=[object Object],[object Object]"
