Adding npm dependency from keybase git repository is not working.

~~~
npm install keybase://private/[username]/[repository]
-> An unexcepted error occured : Invlid URI \"keybase://private/[username]/[repository]"
~~~

This is very important functionality for me : resolving npm package from git repository. But it's not working with keybase url. What can i do?

Reproduce the reported `npm install keybase://private/[username]/[repository]` command and trace where the URI is rejected; the issue names no source file or test. Completion would mean a private Keybase repository can be installed successfully and the behavior is covered by a regression test.
