fix sort columns

If a report is sorting by a ruby field
and the values are cached

Then `record` will not have all the attributes.

We noticed this with power_state, as it was blowing
up on the second page or when sort is toggled

fix is to access the `row` data instead of the `record` data

fixes bug introduced in b1a5e86c013e44
