Ticket #47831 - server restart wipes out index config if there is a default index

https://fedorahosted.org/389/ticket/47831
Reviewed by: nhosoi (Thanks!)
Branch: 389-ds-base-1.3.0
Fix Description: In ldbm_instance_index_config_enable_index(), only call
the function ldbm_index_parse_entry() if the index does not exist.  Instead,
get the name of the index from the "cn" attribute of the entry, and use
ainfo_get() to get the index.  If this returns NULL, then call
ldbm_index_parse_entry() to create and parse the index.
