#1166)

* Add a test that ensures the read is txn read

When doing a readOnly transaction, the code should do reads from a consistent snapshot so that if a write is done mid-transaction then that doesn’t affect the read value.

* Code change that lets test pass

This code change ensures transactions that run aggregate queries actually make the request as an aggregate query.

* Add a test to verify run query results

Verify run query results at a particular time so that we know what data we are working with for the rest of the aggregate query tests.

* linting fix
