Add negative tests about update-volume API

As the following part of API-WG guidline[1],

 If a request contains a reference to a nonexistent resource in the
 body (not URI), the code should be 400 Bad Request. Do not use 404
 NotFound because :rfc:`7231#section-6.5.4` (section 6.5.4) mentions
 the origin server did not find a current representation for the
 target resource for 404 and representation for the target resource
 means a URI

Nova should return a NotFound(404) on this first test case, but it
should return a BadRequest response(400) in this second case, because
the second volume id is specified in a request body.
