There is a JS warning raised by DT which makes the tests fail:
```
The following error originated from your application code, not from Cypress.
> DataTables warning detected in log: "DataTables warning: table id=holdings_table - Ajax error. For more information about this error, please see https://datatables.net/tn/7"
```
It is caused by a 404 returned by the API, because DT receives the
response during the afterEach (after the objects have been deleted)
We must wait for the responses when needed.
Test plan:
cypress run --spec t/cypress/integration/KohaTable/Holdings_spec.ts
should still pass
