RUBY-529 raise exception for multiple attempts to auth on the same db

Server side, MongoDB will log out the first user when a second authentication
is issued for the same database. In the past we've handled this by just quietly
updating the authentication credentials we have stored for that db.

The driver spec for auth now requires that we raise an explicit exception so
that users don't unknowingly log out previous authentications applied to the
database.
