Fix bug for the bestScatter tolerance in Velo tracking
Bug fix in Velo tracking. The tolerance to use for the Extrapolation and accept the hits was used correctly only for the same side search of the module but not in the change side. The change will improve a bit the tracking efficiencies. Concerning timing for the HLT1 it's not trivial to say. You can save time because you find hits on track, thus you flag, thus you save loops later or, the window being larger brings extra calculations.
