Bug fix to an "OR" logic in tau discrimination

[mbluj]

Fix to an initialization of passesPrediscriminants variable to make OR logic working properly. In current implementation True is always when mode with logical OR is selected.
It is an urgent bug fix required for new HLT paths with taus. The OR logic is not used in default reco sequences.

and another one with a messed up ref, trying to merge 4233

fatal: Couldn't find remote ref refs/pull/4233/head

need to do mbluj:fixOrLogic

[slava77]

@ktf
Giulio, did you ever get a feedback from github about broken refs ?
#4233 and #4209 have this problem

[ktf]

Yes. They changed some internals and have now a new (official) way of getting PR refs. I need to try it out and change it, but not before next week.

[slava77]

+1

for #4233 f7e6e37

tested in CMSSW_7_1_X_2014-06-12-0200 (test area sign710a)

everything is OK: no diffs (neither in reco nor in HLT, whatever is monitored in DQM/Validation)

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_1_X IBs unless changes or unless it breaks tests. @nclopezo, @ktf can you please take care of it?
