Cleanup: remove reply and request member variables in QMLManager

The reply member variable was used to access the reply in the
handleSslErrors, handleError and retrieveUserid slots. This is a
very scary proposition in the light of multi-threading. Instead,
the reply can be accessed by using the QObject::sender() function.
Thus, we can remove the member variable.

The request member was just downright weird. This was only used
locally to describe a network request. Since QNetworkAccessManager::get()
copies the request, it can be destructed right away. Nevertheless,
the data was kept as a subobject. Remove member and make it function-local.
