[RM-6447] first pass results are wrong

Created on 2021-04-14 07:24:06 by Didier Vibert. % Done: 100

when dealing with #6340 I have seen a bug in the way the hdf5 outputs are getting the first pass results. These results are in the resultstore, but the global @COperatorResultStore::getCandidateData@ which are calling the derived function on each result is wrong for the first pass results. There are taken from the final result @linemodel_extrema@ in the resulstore instead of the first pass results (@linemodel_firstpass_extrema@) and are thus equal to 2nd pass results).

we can either:

• correct for this right now ( the fix seems easy, since all the 1st pass hdf5 attributes have their name beginning with the string "FirstPass" we can check for this in @COperatorResultStore::getCandidateData@ and call the derived @getCandidateData@ on the correct result (@linemodel_firstpass_extrema@)
• wait for #6343
