We don't key it on IP address anymore so we can drop
the use of QMultiHash.
This also requires moving the connections for error and disconnected
to readyForUse so we don't remove an active connection when a second
connection attempt happens from the same peer process.
But since we still need to deallocate those connection attempts
if they error out or simply disconnect, we connect their signals to the
QObject::deleteLater slot. In some cases we might call deleteLater twice
but that's fine.
