fix: db transaction errors caused by checkDocumentLockStatus (#11287)

Just like #11269, we stop passing through `req` to db operations in `checkDocumentLockStatus`.

After extensive testing, this seems to get rid of all transaction errors that occurred when I was testing autosave against a remote mongo DB.

We keep the `req` for postgres, as it mysteriously breaks in CI - this cannot be reproduced locally
