MatCalibration: add fallback solution for missing conditions

This adds empty values in the case of missing conditions from old versions of conditions files for the SciFi mat end contraction calibration.

Without this it would be required to manually set a flag to enable the calibration, which is undesirable.

Goes with Rec!3693 (merged) and Alignment!453 (merged)

changed milestone to %Developments targeting restart after May MD

added Alignment RTA labels
