[PATCH v7 8/9] connect: actively reject git:// urls with a user part

Currently, urls of the for git://user@host don't work because user@host is not resolving at the DNS level, but we shouldn't be relying on it being an invalid host name, and actively reject it for containing a username in the first place.
