Fix crash on subscriptions

When the subscription limit is hit, there is Subscription events
generated when Subscription objects are constructed.  Unfortunately, we
make an accidental copy of the Subscription object in
include/persistent_data.hpp

https://gerrit.openbmc.org/c/openbmc/bmcweb/+/72670

Is lined up to fix that issue, but we need to fix the underlying problem
where we have memory safety issues in global variables.

This commit is something to fix the issue, by simply destroying the
object causing the problem before more events can be received.

Tested:
Followed instructions on the aforementioned commit to create the max
number of subscriptions.
Called systemctl restart bmcweb

Observed no more crash on shutdown.
