FIX: fix ids rake task should be evaluated only once (PR #76)

If you run rake task twice it will throw an error because the temporary table will exist.

That rake task should be idempotent

We need to clean this up if the tables have been left around in the database.

The title of this pull request changed from “FIX: fix ids rake task should drop temporary tables if exists” to "FIX: fix ids rake task should be evaluated only once

Let’s unblock ourselves with this fix first but I think we should continue to investigate why the rake task has been loaded twice.
