Description
Added missing case in switch, to make the second call to set-accession finish and not loop infinitely. The fact that the accession id is already set, will later be caught by another check and (hopefully) handled as intended there.

How to test

1. At the root of the repo, start the stack by running

make build-all
PR_NUMBER=$(/usr/bin/date '+%F')  docker compose -f .github/integration/sda-s3-integration.yml run integration_test

2. Set the ENVs by

export ACCESS_TOKEN=$(curl -s -k http://localhost:8080/tokens | jq -r '.[0]')
export API_HOST=http://localhost:8090

3 . Ingest a file and set the accession id twice

./sda-admin file ingest --filepath requester_demo.org/data/file1.c4gh --user [email protected]
./sda-admin file set-accession --filepath requester_demo.org/data/file1.c4gh  --user [email protected]   --accession-id my-id1 
./sda-admin file set-accession --filepath requester_demo.org/data/file1.c4gh  --user [email protected]   --accession-id my-id1 

4. Make sure the logs look ok and that the file's status in the db is good.
