dbus-manager: Keep application alive for operations

Operations started from Nautilus windows have the persistence handler,
however, when not using windows like when invoked through DBus the
application could die after a timeout.

This would stop the operation in the middle of its process, with
possible data loss.

Make sure we keep the application alive while this is happening.
