Fixed the functional test lib function that unconfigures an ssl connection.
Previously, the ldaps connection handler was diabled and the key-manager-provider-dn and the trust-manager-provider-dn values were rest all in one dsconfig operation. 
Now the ldapsconnection handler is disabled in one dsconfig operation and the  key-manager-provider-dn and the trust-manager-provider-dn values are reset in a separate dsconfig operation.
