[O2B-1201] Extract lhcPeriod from patch and not relations (#1472)

Notable changes for users:
- At the first SB today, we have observed an issue in which lhcPeriodName was not being saved in Bookkeeping

Notable changes for developers:
- this was due to the lhcPeriod string from ECS being extracted from relations instead of patch which resulted in a null lhcPeriod being saved
