- Removing existing listener that was backfilling created records
without position
- Switch to a job that backfill all objects within workspace
- Adapting `FIND_BY_POSITION` so it can fetch objects without position.
Currently we needed to input a number
- refactor record position factory and record position query factory
- override position if not present during createMany
To avoid overriding the same positions for all data in createMany, the
logic is:
- if inserted last, use last position + arg index + 1
- if inserted first, use first position - arg index - 1
