SOQLDatatable delete_row action has confusing error message when Name field wasn't queried

When a soqldatatable does not query for the Name field, if the `delete_row` action is used, the confirmation dialog asks `Are you sure you want to delete "undefined"?`

This error message could be confusing to the user. Perhaps it could be switched to `Are you sure you want to delete this record?` if the Name field is not available.

Thanks!
