Checks that performing a transformation on a relationship that is *not* the
result of a natural join, results in a relation with fields that are
populated as expected.
@param {!lf.schema.Column} aggregatedColumn The column to be calculated.
@param {number|!Array<number>} expectedValue The expected value for the
    aggregated column.
@param {!Function} assertFn
