Test to check second replica installation after master restore
    
    When master is restored from backup and replica1 is re-initialize,
    second replica installation was failing. The issue was with ipa-backup
    tool which was not backing up the /etc/ipa/custodia/custodia.conf and
    /etc/ipa/custodia/server.keys.
