Remove ROBDataProviderSvc EventContext fallbacks and adapt clients
ROBDataProviderSvc kept the old interfaces, e.g.
getEvent() {
return getEvent(Gaudi::Hive::currentContext());
}
These are not picked up by the static checker. Remove the old interfaces and adapt all clients. In many cases the ROBDataProviderSvc methods are being called from functions that already have an EventContext.
