Error Handling Issue When Suborg Level Parameters Reference Non-Existent Teams

When changing a parameter at the suborg level, such as `suborgteams`, to a non-existent team, the system returns an unexpected value.
```
# List of repos that belong to the suborg
suborgrepos:
- test-repos*
# You can use Glob patterns

suborgteams:
- test-team
```

The pod logs indicate an `HttpError: Not Found` error, which is logged as:
```
{"level":50,"time":1725518921172,"pid":25,"hostname":"safe-settings-c687bc859-x9c5d","name":"probot","name":"probot","name":"event","id":"e0970a60-6b52-11ef-9f7d-55142efd27bc","msg":"NOPCOMMAND {\"type\":\"ERROR\",\"plugin\":\"getSubOrgConfigs\",\"repo\":\"safe-settings\",\"endpoint\":\"\",\"body\":\"\",\"action\":{\"msg\":\"HttpError: Not Found\",\"additions\":null,\"modifications\":null,\"deletions\":null}}"}
```

We used release 2.1.10, but the issue also occurs in versions 2.1.11 and 2.1.12-rc.1.
