Fixes #2384

Note: The fix is a little broader than just the parameterized ClickHouse queries, e.g. WHERE id IN {ids: Array(UUID)}.

After opening the issue, I experimented a little more with ClickHouse, and found that it wraps in parenthesis anything on the RHS of IN, even for singular values, e.g.

SELECT * from users WHERE name in 'a';
-- becomes
SELECT * from users WHERE name in ('a');
