Fix input parameters for PU-weighted MVAIso

[mbluj]

As title of this PR says it fixes an input parameter for PU-weighted MVAIso tau-Ids. The effect should be seen as (moderate) change of "ByIsolationMVArun2v1PW" tau-Ids.

The changes in the "ByIsolationMVArun2v1PW" tau-Ids are rather evident, being the output of the discriminator much more peaked towards the value of 1, see e.g. RunSinglePh2017B wf 136.788:

The fix is rather obvious, anyhow, and I suppose that the change, although not "moderate" goes in the right direction. Please @mbluj comment.

[mbluj]

The change goes indeed into expected direction.

Regardless, I please find below a set of MC plots for genuine and fake taus as reference.

• PU-weighted MVAIso score for genuine taus in ZTT events
• PU-weighted MVAIso score for jet->tau fakes in QCD events
• ROC for PU-weighted MVAIso tau-ID with genuine taus in ZTT events and jet->tau fakes in QCD events with 20<Pt<120GeV

• it fixes a mis-typed input parameter for PU-weighted MVAIso tau-Ids
• Effects on the tau-id outputs follow the expectation

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
