core (xmpp): adapt message workflow to components: message workflow were not used for components so far. This patch activate it, normalise namespace to the client one to simplify parsing, and use SatXMPPComponent.sendHistory and SatXMPPComponent.receiveHistory to indicate if a component should store sent and received message in database (they both default to False). OTR plugin is deactivated for components. rel 367
