As we discovered in a CMSSW ROOT `master` sync PR, the new RooFit CPU backend treats empty datasets differently from the legacy NLL evaluation backend: cms-sw/cmsdist#9025 This commit is fixing this, in particular removing the assumption that datasets used for fits with the new CPU backend are never empty. A unit test that validates the behavior for empty data objects is also added.
Also, write out "constructor" instead of using the slang abbriviation "ctor".

It was validated locally that the test now also passes with the CUDA backend. |

backend:

This commit is fixing this, in particular removing the assumption that
datasets used for fits with the new CPU backend are never empty.
A unit test that validates the behavior for empty data objects is also
added.
I set the priority to "high" because this is a blocker for CMSSW to use ROOT master.
