Blank keyserver isn't using the default

[micahflee]

In GPG Sync 0.3.0.dev3 in Windows, when syncing a keylist, it imports the authority key to my gpg keyring, but it doesn't import the keys on the keylist.

I think this may not be a Windows problem, but rather a keyserver problem. It looks like this is being treated as a successful --recv-key command, when really it should have failed:
