Title: use parse_nested_query instead of parse_query

when sending url with array parameters, faraday adds additional brackets into the url. so

```ruby
'http://a.co/page1?color[]=red&color[]=blue' becomes
'http://a.co/page1?color[][]=red&color[][]=blue' when request is sent.
```

this patch prevents additional brackets to be added, by calling parse_nested_query instead of parse_query.
