Restarting daemons after upgrading is something the project has been
quite resistant to implementing.  Mostly because as soon as you start
looking into it in any depth the true complexity of doing that sort of
thing reliably for any conceivable system becomes apparent and you end
up muttering darkly about systemd and losing the will to live.

However, yes, restarting slapd -- it's clear that your script does get
called, but slapd fails to start at that point during the upgrade
process.  slapd is well known (at least to me) for failing to start
/silently/ -- you need to check the process is actually there after
trying to start it, and look at the logfiles and so forth.  It also
seems to quit at the slightest provocation, presumably to avoid any
potential for data corruption.

So check you logs to see why slapd didn't start.  It's quite possible
that it was simply that something else that slapd needed wasn't
available at that exact point during the upgrade process, and just
waiting until the upgrade had finished would sort things out.
