This rake task is responsible for fixing broken ids - move them back to the original values - ones before migration to a separate table.
Rake task can only fix queries with unique names.
In the test, we are creating duplicated queries and using `original_id` 4. Spec is ensuring that after rake tasks valuation, queries id is different than `4`
However, spec run in random order may create a query with id 4 and in that case, the spec would fail.
Therefore, when we create queries for test purpose, we should control what ids they are given to avoid conflict.
Reintroduces the migration removed in `cdfc5d4`, and fixes it to work with `query_groups`. Since the code is fairly complex, I moved into a rake task so it can be tested and make sure it works.
