Pkp-lib: Fatal error related to subscriptions when merging a user

[NateWr]

When merging a user, I got a Fatal Error that seems related to subscription details:

[Tue May 01 15:31:46.285506 2018] [:error] [pid 15251] [client 127.0.0.1:37120] PHP Fatal error:  Uncaught Error: Call to undefined method IndividualSubscriptionDAO::deleteSubscriptionById() in /var/www/html/ojs/classes/subscription/IndividualSubscriptionDAO.inc.php:317

It didn't happen with every user, so it seems to be related to some specific configuration of subscription data (or lacking data). Maybe you have some idea @asmecher?

Ah, I first now see this -- it is solved and merged with this issue https://github.com/pkp/pkp-lib/issues/3664. Thus closing...
