title: Kotlin unable to pass get request parameters (Fuel library)
body: <p>For this simple example taken straight from the <a href="https://github.com/kittinunf/fuel/blob/master/fuel/README.md" rel="nofollow noreferrer">docs</a>:</p>
  
  <pre><code>Fuel.get("https://httpbin.org/get", listOf("foo" to "foo", "bar" to "bar"))
      .also { println(it.url) }
  </code></pre>
  
  <p>This prints out <code>https://httpbin.org/get</code>, as opposed to <code>https://httpbin.org/get?foo=foo&amp;bar=bar</code></p>
  
  <p>How do I fix this? I'm using <code>fuel 2.1.0</code></p>
