Moving HLT_e26_lhtight_nod0_ivarloose_L1eEM22 from primary_single_ele to primary_single_ele_iso
This a follow up of !22261 (merged) to add the chains HLT_e26_lhtight_nod0_ivarloose_L1eEM22 HLT_e24_lhvloose_nod0_L1eEM20 HLT_g25_medium_L1eEM20 in our monitoring as requested in ATR-19610.
There was a typo there and am moving HLT_e26_lhtight_nod0_ivarloose_L1eEM22 from primary_single_ele to primary_single_ele_iso. Thanks @aranzazu for pointing it out!
