Looks like the simplest "fix" would be to add constructors with ```edm::ConsumesCollector& iC``` parameter to ClusterChecker and GlobalTrackingRegionProducerFromBeamSpot and use that in here (changing the type from ```&&``` to ```&``` would not work (=be simple) because of inheritance and plugin factory, and the desire to use ```constructor(consumesCollector)```).

Should I make a new PR or include the fix in this one (or will somebody else take care of it)?
