Deleting a dataset raises an 500 server error in requests dashboard

[danmihaila]

We faced the following scenario

1. Create requestable dataset
2. Request it
3. Delete it
4. Go to dashboard

Result is error 500 server error, the controller is trying to package_show an id that is purged. What is the best approach?

1. when dataset is deleted, it should delete also the requests?
2. don't allow a dataset to be deleted
3. send an email to all requesters before deleting dataset and all requests

We didn't notice this scenario, nice point @danmihaila .
I think the best approach will be before deleting the dataset notify all of the requesters and after that delete dataset and requests for it.
