fixed getters to be able to read from miniAOD

[jpavel]

Bug fix for the pat::Tau accessor functions that use pfSpecific(). This function (rightly) returns cms::error, when ones tried to read from miniAOD because pfSpecific is not filled by patTauSlimmer. This bugfix introduces check for the existence of pfSpecific before accessing it.

Tau POG considers this bugfix critical for CSA14 - without it the analysis of taus in miniAOD will not be possible.

No change in physics output is expected.

@jpavel Okay. So in miniAOD, (tau) PAT object is created from (tau) PAT object basically.
Did we have already 71X and 72X for this fix?

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_0_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?

[jpavel]

@monttj Thanks for signing - there are no PR's for 71x and 72x yet, but as the change is trivial (one file), I will prepare them asap

[jpavel]

So 2 new PR's created: #4466 (for 71x) and #4467 (for 72x)

Hi Pavel, thank you!
