Tomaz Canabrava 0dd40b7a51 Rely on QNetworkReply finished() signal instead of AccessManager one
The access manager is only one, while we can make requests from
different parts of the application, so relying on the manager
finished() signal to see if something was done or not was a
not very good move.

The QNetworkReply is created when a get() is invocked on the
AccessManager and that's unique. connect it's finished()
signal instead.

bonus: code cleanup.
