Setting resolver_match in current request

[sspross]

Hi @raiderrobert

We're using your multiurl library, thanks for that btw :) While using we ran into the problem of not having the right request.resolver_match later. For e.g. reverse the current request url in another language like url = reverse(request.resolver_match.view_name, kwargs=request.resolver_match.kwargs).

My provided fix solves this and I might be wrong but I think it is done similar to how django does this internally, see https://github.com/django/django/blob/bff5ccff7501d7bafb53d6110e311882e716bee5/django/core/handlers/base.py#L102

Let me know if you need more added to this very simple pull request :)

Best regards,
Silvan
