Not all action logs are migrated into analytic engine

[Alexander Kislitsky]

Migration strategy of action_logs to Elasticsearch should be changed:
1. composite key should be used for action_logs for generating Elasticsearch _id value
2. we should handle migration of action_logs with Null value in DB field, used as marker of last synced object
