corrupt 68ceb17272 chore($httpBackend): preserve original non-zero http status code for file:// apps
Previously if an app was running from file:// origin we would always return either
http 200 or 404 depending on whether the response was present.

This changes the behavior so that we do this only if the protocol of the request
(not the origin) is file:// and only if the status code is 0.
