Fixed #16087 -- Added ResolverMatch instance to test client response

@timgraham would `django.utils.functional.SimpleLazyObject` do the job here?

``` python
try:
    resolver_match = SimpleLazyObject(lambda: urlresolvers.resolve(request['PATH_INFO']))
except urlresolvers.Resolver404 as e:
    resolver_match = None
response.resolver_match = resolver_match
```
