FlavorTagDiscriminants: do not bail out in VRJetOverlapDecorator for events with less than 2 track jets
In the VRJetOverlapDecorator, currently the jets are not decorated with the overlap information. Although this is resourceful, it presents a problem for downstream analysis code which expects decorators to be present on every track jet.
This MR removes a line causing to bail out of the code and consequently results in all track jets having the decorators attached.
