tests: Fixed method failures during second call for the method

When the same host is used for numerous server/replica
installations/uninstallations at some point the /etc/openldap/ldap.conf file
gets corruped which results in ldapsearch unaware of the default ldap_uri to
connect. The workaround would be to provide ldap hostname for each ldapsearch.

Attention: please unapply this fix once the original issue is resolved.
