Contracts validation can be not correct when `query_settings` used

[oleg-savko]

Contracts validation can be not correct when query_settings used:

when use for example like this:

query_settings={
            'join_use_nulls' : 1,
}

they seems not used here:

dbt-clickhouse/dbt/adapters/clickhouse/httpclient.py

Line 31 in 8897ecb

query_result = self._client.query(

and macros which check columns types failed, but real table and contract actual matched

P.s: if add at the end settings join_use_nulls = 1, than contract validation passed normal
