Set mva tight value of initial step to be equal to highPurity mva (76X version of #12223)

[istaslis]

76X version of PR #12223.
This PR changes mva value of 'tight' selection of HI initial step reconstruction. This is a minor fix to prevent confusion and it does not change the event content (because subsequent steps are dependent on 'highPurity', not 'tight' selection)

For #12230 ba2267f

Adjusting the tight MVA value of the Heavy Ions initial step. There should be no change in monitored quantities. #12223 and #12231 are the 75X and 80X versions of this PR, and the latter has been approved by Reco.

Jenkins tests against baseline CMSSW_7_6_X_2015-11-02-1100 show no significant differences, as expected.
