I don't see any particular reason here to allow the transaction apply
to complete if the subscription is disabled. Note, that here we are
waiting at the beginning of the transaction and for large
transactions, it might cause a significant delay if we allow applying
the xact. OTOH, if someone comes up with a valid use case to allow the
transaction apply to get completed after the subscription is disabled
then we can anyway do it later as well.
