Rename test case class for AuraRouter
Change http method detection

Now method is determined by following order:
1. routing value $route->values['method']
2. $_GET['_method'] if $_SERVER['REQUEST_METHOD'] is 'GET'
   $_POST['X-Http-Method-Override'] if $_SERVER['REQUEST_METHOD'] is 'POST'
3. $_SERVER['REQUEST_METHOD']
Method override via X-Http-Method-Override header

Now, it allows method override via X-Http-Method-Override HTTP header.
Add testing for query parameter handling.

The additional test sure that AuraRouter::match()[2] includes query parameter.
