Fix sorting the Review ID column with the new LocalSite ID changes.

The Review ID column was using a function to get the proper ID for a
review request, but functions aren't sortable in the database. This
broke at least one user. Instead, construct the column with the proper
field.
Tested sorting with both IDs.
