fix: fix output of RPCs returning scalar values with multiple rows

resolves #1584 BREAKING CHANGE: Changed output of RPCs to match return type better: * single scalar return: value (unchanged) * setof scalar return: array of values (new; was array of objects) * single composite return: object (new; was array of objects) * setof composite return: array of objects (unchanged) * void return: nothing (new; was "null") A single OUT column is now treated as "composite" instead of "scalar", i.e. consistent with multiple OUT columns.
