Fix specs reload with ignored_columns

The specs pass using `reload` in both actual and expected because
`ignore_columns` is not working as expected.

We don't use `reload` anywhere in the integrations code, so we can go
with `reload` in the specs because the comparison having the ignored
columns match with the extra columns.
