title: swagger-test says invalid URI on valid swagger-spec
body: <p>I noticed that swagger-test needs my "host" element in the swagger-spec to be like this:</p>
  
  <pre><code>http://api.myservice.io
  </code></pre>
  
  <p>Rather than what the swagger spec requires, i.e.:</p>
  
  <pre><code>api.myservice.io
  </code></pre>
  
  <p>This means that swagger-test would read my final URI as invalid if I use the swagger-spec notation. While if I use the swagger-test notation, swagger-core will end up reading something like http//:http//:api.cloudboost.io, still ending up invalid.</p>
  
  <p>Is this intentional or am I missing something?</p>
