Remove 389-ds upgrade state during uninstall
When we perform an upgrade 389-ds is set to listen only on its
ldapi port. Theoretically it should be restored to the previous
state regardless of whether the upgrades were successful or not.
To be sure that a subsequent re-install will be successful go ahead
and remove the state for these options. Think of it as wearing a
belt and suspenders. Otherwise a re-install could return an error
message that IPA is already configured.
