New member finished' in EShellOfflineHandlerPrivate'.

* e-shell-offline-handler.c: New member `finished' in
`EShellOfflineHandlerPrivate'.
(finalize_offline): Ref the handler as we might get destroyed
while putting every component offline.
(impl_OfflineProgressListener_updateProgress): Don't emit
::offline_procedure_finished if ->finished is %TRUE.  Also, set it
to %TRUE after emitting the signal.
(cancel_offline): Likewise.
(finalize_offline): Likewise.
(update_dialog_clist): Guard against NULL ->dialog_gui.
