Change URL to get Provider, add method find all locations #1

it is not what I meant, we should have method for getting `current_pagination_page`

```ruby

def current_pagination_page
  pagination.children[1].text.strip.scan(/^Page ([0-9]+) of/).first.to_i
end

```

and this line would be

```ruby
return @page if page_number == current_pagination_page
```
