BigQuery project alias is ignored in config

[drewbanin]

Describe the bug

A user reported that a config like:

{{ config(project='myproject') }}

...

has regressed in dbt v0.17.0. While this config worked in a BQ project in dbt v0.16.1, they reported that they needed to change project to database to apply the configuration in dbt v0.17.0.

This issue needs to be reproduced - there may be other factors that impact the incidence of this regression.

Steps To Reproduce

-- models/my_model.sql

{{ config(project='custom_project') }}

select 1 as id

dbt run

Confirm that the model was not build into the custom project override

Expected behavior

The model should be built into the project defined in the project config. Database-specific aliases should applied to config names.

System information

I can reproduce this in a test.
