Fix use-after-free of QNetworkReply in BaseJob
Usually QNetworkAccessManager expects the user to delete the replies, but when the QNetworkAccessManager itself is deleted it deletes all pending replies (https://code.woboq.org/qt5/qtbase/src/network/access/qnetworkaccessmanager.cpp.html#529).
This can lead to use-after-free crashes when d->reply is accessed. By putting the reply into a QPointer the exiting if(d->reply) checks can work properly.
(cherry picked from commit 9d854e778d8d6ef8e03e1ea74fe958675b24fd45)
