Checklist

• Self-review the PR after opening it to make sure the changes look good
  and self-explanatory (or properly documented)
• Add relevant issue to release milestone

Testing instructions

• Navigate to the Query Builder (QB).

• Select a table that you know has one or several aggregators (To check, go to app resources, navigate to Record Formatter, choose the table, select aggregator tab, and verify the list of aggregators names available).

• Choose "aggregated."

• Verify that in the query line, after selecting the "aggregated" field box, a drop-down appears with a list of aggregators choices (corresponding to the list in app resources).

Verify that changing the aggregator changes the way the field is displayed in the results table.

The problem seems to be that the back-end is ignoring the formatter name in the request. It is just getting the aggragator and then getting the formatter that the aggregator is pointing to. I changed the code so that it takes into account the 'formatter name' that is passed in the query builder request.

Changing the aggregator does not change the way the field is displayed and seems to only show the default aggregation.

Looks good, changing the aggregator changes the results now!
