I thought it would be better if we don't restart the worker unless it
is required. In case, the subscription's owner is a superuser, the
'password_required' is ignored, so why restart the apply worker when
somebody changes it in such a case? I understand that there may not be
a need to change the 'password_required' option when the
subscription's owner is the superuser but one may first choose to
change the password_required flag and then the owner of a subscription
to a non-superuser. Anyway, I don't think as such there is any problem
with restarting the worker even when the subscription owner is a
superuser, so adjusted the check accordingly.
