handling the case where caliper is run in init, but not in libval

In some cases (U.Pettersson_14_01) , the Caliper process is run durint the initqc steps, but not during the library validation. PSUL looks for a caliper step in validation, doesnt find one, and looks back until it finds the one in initqc, marking it as libval.
the check will ensure that the caliper process happened after the preparation.
