Code review comment for lp:~aaronp/rnr-server/delete-review

Yeah, that makes sense, technically in the client the user should not be allowed to delete the review if it's already deleted or if it's not theirs, so it may be overkill to cater for it here. I'll implement using the get_object_or_404 and we'll see how it goes. If it's coded well enough in client (which it might not be - remember I wrote the code!!) then it shouldn't be an issue.
