Fix for mu_CombDLLmu_IsMuon sample for Run 1
Cutstrings supplied in the Run1 Config are not applied in the MakeTuples.py script. This merge request fixes this issue for the function "convert_single_file" but does not do it in the function "convert_calo_file".
In the Run1 Config the cutstring is also given incorrectly. This is also corrected for in the merge request.
