[24.1] Also check dataset.deleted when determining if data can be displayed

[mvdbeek]

This is being called when serialising HDAs in the poller if the HDA is expanded.
When we purge via celery we set the HDA to deleted, flush and purge async, so it is possible that the async task removes the dataset from disk while the ORM object in the poller still is in non-purged state.

I think this fixes

The error occurred at the same second as the last update to the history_dataset_association.
