Fix Unregistration of transfered repos

[samccone]

Steps to reproduce

• create a repo under user X
• user X registers the repo on bower github.com/X/foobar
• user X transfers the repo to user Y
• user Y wants to change the registry to a new location
• user Y tries to unregister (however it fails)

This is because of

var owner = pathParts[1];
var repo = path.basename(pathParts[2], '.git');

https://github.com/samccone/registry/blob/master/lib/routes/packages.js#L43-L44

Which pulls the contributors from the original registration url instead of the updated location of the project (since it has been moved).

Solution

• The simple solution here, is to make sure that when you get the http version of the repo, it does not 301 redirect to the new repo

For instance:

curl -I https://github.com/marionettejs/testing
HTTP/1.1 301 Moved Permanently
Server: GitHub.com
Location: https://github.com/samccone/testing

Clearly the permissions should be checked against samccone/testing

These are just my thoughts after chatting with @desandro, let me know If I am missing something or whatnot. 👍

The ultimate goal here is to unburden the people that have been doing a great job manually doing the unregistration over at bower/bower#120
