Handle an empty base_dn and no cn=ipaconfig in the ldap2 backend, fix migration.

We lacked good error messages if the user/group container you used doesn't
exist.

Add a --continue option so things can continue if you use a bad user/group
container. This has the side-effect of letting you migrate just users or
groups by using a bad container for the one you don't want.

Fix a Gettext() error when displaying the migrated password message.
