test: fix updatedAt test

In some cases, the test failed with assertion error, because it compared expected with passed updatedAt on a new record (no id), whereas for new records a updatedAt is generated in the constructor.

```
AssertionError: expected '2024-01-18T16:23:59.276Z' to equal '2024-01-18T16:23:59.275Z'
```
