Apply query settings for empty table model

[alexsubota]

Summary

Fix for query_settings
Currently, when a table is created, the query settings are not passed to the query, which causes an issue with the join_use_nulls setting (empty table have not nullable column, and then we cant insert null into this column). This PR fixes this behavior.

Is it possible to add a test case? It's probably okay but can't tell by looking whether (for example), the contract logic interferes with the query.

i can create test model like this

{{
    config(
        materialized='table',
        query_settings={
            'join_use_nulls': 1
        }
    )
}}
select t2.id as test_id
from (select 1 as id) t1
         left join (select 2 as id) t2
on t1.id=t2.id

and check that test_id has a nullable type.
Is it ok?

@genzgd check test please

@genzgd I checked locally and it doesn't collide with the contract (from a syntax point of view).
