Issue 50823 - dsctl doesn't work with 'slapd-' in the instance name
Bug Description:
DirSrv.list drops all occurrences of 'slapd-' within a serverid
rendering names containing it damaged.
Fix Description:
Remove only the first occurrence of 'slapd-' in the serverid, which is
the prefix that is expected to be removed.
