Revert wrong use of 'RichCalibratedDLLX' values

A recent update in LHCb added RichCalibratedDLLe and RichCalibratedDLLmu variables to the ProtoParticle AdditionalInfo. These variables (badly named, the values aren't calibrated in any meaningful way but just scaled) should only ever be used when adding the RichDLLs to the combined DLL values. The scaling applied is done simply to make the range of the values better match those other sub-systems create. They should not be used anywhere else and instead the original unmodified values from the Rich should be used. This MR reverts the wrong usage back to those original raw values.

Thanks to @tnanut for drawing my attention to this.
