List resource ID instead of distribution ID in datastore import dashboard

[dafeder]

The datastore import dashboard has a column called "resource" but shows an identifier which is actually the distribution ID. Aside from this just being a straight-up incorrect label, it's not clear that anyone needs the distribution ID; the resource ID is what you would want to copy to use with Drush commands on the datastore. SO let's swap the distribution UUID for the actual resource ID.

Would be nice if we could include a little clickable [copy] icon too.
