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

This is being called when serialing HDAs in the poller if the HDA is
expaneded.
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
