Modified testing condition, special chain cases treatment implemented
- Adding special cases "HLT_e26_lhmedium_nod0_mu8noL1" and "HLT.*tau.xe." which need different than default testing
- Correction of multiplicities and chain leg ID assignemnts to TE elements for "HLT.*tau.xe."
- Modification of testing condition in such a way that matching of Run2 and Run3 is on a level of objects, instead of group of objects
