RemoteMenu: Avoid useless signal connections

Browse Source 
If we are missing more than one action, every time action-added is
called, it calls modelChanged() again and re-connect signal for
all action still missing. This patch prevent from connecting signals
again when doing a refresh because a missing action is now available.
All necessary signals have already been connected.
