ipatests: backup-reinstall-restore needs to clear sssd cache
The integration tests that check backup-reinstall-restore
scenario need to clear sssd cache before checking the uid
of the admin user. For instance:
backup: saves the original admin uid
reinstall: creates a new admin uid, potentially cached by SSSD
restore: restores the original admin uid
