ConnectionEditorBase::initialize() does not count the number of pending dbus
replies, so it is currently assuming that if control reaches the end of the
function, we are not waiting for secrets and we can claim the kcm is
initialized. That is not necessarily true, as bug #376739 shows.
If we count the number of replies actually received, we can be sure that there
are no more pending replies and we can then set m_initialized to true at the
end of initialize().
