title: $httpBackend with request with query param
body: <pre><code>$httpBackend.whenGET('/restpath/api/v1/books')
  .respond({// some data}); 
  </code></pre>
  
  <p>I get the following error </p>
  
  <pre><code>Error: Unexpected request: GET /restpath/api/v1/books
   Expected GET /restpath/api/v1/books?limit=10&amp;start=1
  </code></pre>
  
  <p>For the expectGET I have the following , and this creates dynamic query string. mostly the 'start' parameter, and the whenGET part, I am trying to server a dynamic content depending on the 'start'</p>
  
  <p><code>$httpBackend.expectGET('/restpath/api/v1/books?limit=10&amp;start=1');
   // the actual service goes here , which does the $http service. we don't care
   $httpBackend.flush();
  </code></p>
