The same aggregator can have two output names for a SQL like:
```
INSERT INTO foo
SELECT x, COUNT(*) AS y, COUNT(*) AS z
FROM t
GROUP BY 1
PARTITIONED BY ALL
```
In this case, the SQL planner will create a query with a single "count"
aggregator mapped to output names "y" and "z". The prior MSQ code did not
properly handle this case, instead throwing an error like:
```
Expected single output for query column[a0] but got [[1, 2]]
```
