Title: [48480747] fix crash when deleting opening with interviewers assigned

We need an 'id' column for join_table 'opening_participant' so the children can be auto-deleted when deleting parent.

Add an id column for table opening_participant. Since this change is sort of destructive, so merge scheme definition to force history drop.
