Ticket #47420 - An upgrade script 80upgradednformat.pl fails to handle a server instance name incuding '-'

Bug description: If a server instance name contains '-', e.g.,
slapd-TEST-SERVER, it accidentally picks up the first part of
the instance name 'TEST'.

Fix description: Replacing "split(/-/, $instancedir)" with
"split(/-/, $instancedir, 2)".
